The significance of the grab of Zero in the trailer. Does that mean they're actually in this game, or was that just to remind us about 999? If Zero is mentioned, is it a different Zero, or the same one? Very interesting....

IF the game is June/Santa's bigger plan, could they turn up? Wonder who the Grandpa guy is? It would indeed be interesting if Junpei became an Ace-like figure.

It's probably likely this is June/Santa's bigger plan... but what if its a prequel? If we consider the first Nonary game was Past Akane sending Junpei information so he could help save her future self, then the people such as Alice will be how Past Akane remembers them..? If the next game is in the future does that make Alice a real person?

The names arent based on Greek letters - but numbers. We already have Sigma (apparently 200) and Phi (500).
I dont think the rabbit will be Zero (someone said something neat about - maybe it is a reference to the rabbit in Alice in Wonderland, or "All-ice" in Wonderland... - as to the picture of Zero, not sure if he will be in the game or not.. it may just be referencing 999, perhaps Zero will be a suspect.
Maybe this time, theyre on a space station? (Look at the image of a red planet in space). Maybe they're infected with a virus.

At about 0:44, the girl lying down (older June?) isnt wearing a bracelet! :o
The bracelets seem different this time - the number on them is smaller and to the right. Perhaps there'll be more information on the bracelet this time?

this game is Santa's/Akane's bigger plan, but does this actually take place after or at the same time as 999? Surely it would have to be after?
Maybe the "Akane" that decided to become Zero isn't the "real" Akane?
Also look at Phi's "I don't know why, but somehow I know" in the trailer.
Does that sound similar to 999's "Why do I.. know?" line or what?

We don't really know when the game takes place, but I think it should be safe to assume it takes place after 999. I mean, if the game isn't about Santa and June's bigger plan, I really can't think what it would be about (because what would be the point of another Nonary Game? Unless this isn't a Nonary Game, but I think it probably is, although with some changes).
Morphogenetic fields again, I guess? Hmm... I was going to say "what if Phi is actually related to Santa and she's receiving information from him", but Santa was a "receiver", not an "emisor", right? He probably isn't very good at sending information through the fields, unless he has a special talent, like June, which wouldn't be that weird I guess.

Anyway, I think 999's Akane was the real deal. I can't think of any reason why she wouldn't be the real one.

If that is really Clover/Clover spawn then I hope she was captured halfway through changing into her cavewoman costume for a Halloween party because that is so much midriff to wear in public

Perhaps she's the old man's wife or something? They look about the same age... or maybe she's related to the first Nonary Game in some way? The only people who died in 999 were the ones who were related to the first Nonary Game...
It's a bit weird that they're showing us a dead body so early on, even if it happens really early in the game or something like that (like the 9th man's death).
Or maybe her death really is relevant and/or it happens late in the game. It's still weird that they show that in the scan, though.

with its themes of time-loops, choosing the right paths... also a group of strangers being on an old fashioned boat, and the way it played with time...
Doesnt the dead lady look like a much older June? :o

Santa: Look, if you trust anybody in this game, you're gonna lose. The person you trust the most could turn out to be the one who stabs you in the back.

Remember June made the 2nd Nonary Game exactly as the way she saw it through Junpei's eyes in the 1st one. So I don't know if Alice is real or not?

Alice was on the original Gigantic, right? So would she not have sank with the ship?

It is never confirmed that Alice even exists. Ace never found her on the Gigantic, and she didn't appear in any of the coffins in Q building either. In the end, Junpei and the rest starts to reject the idea that Alice exist. If memory serves me right, Ace said something like that as well.. but.. then we see her at the end of the game out in the desert. The creator admitted in the Q&A section (again, unless my mind is playing tricks on me) that the appearance of Alice in the end was just a tease.. so the woman in 999-2 might be Alice, but perhaps Alice has nothing to do with the game at all..
My theory is that the woman we see in the desert is the same person we see in 999-2.. whether or not it is Alice I'm still not sure but I am pretty sure that the woman in 999-2 is supposed to look like the Alice we imagined. My reason for this is of course, the fact that the woman in 999-2 shares the same haircut and the same facial structure as the picture of the "egyptian princess" we see when June tells us about her behind door 4. Also, it's hard to tell from the picture (because the egyptian princess cover her clothes with her arms), but their clothes seem to be the very same.

Here's a crazy theory (read at your own risk).. what if this game is a prequel, and Ace perhaps got inspired by an even older Nonary Game (although this isn't really another Nonary Game) and this game takes place in a laboratory of some sort where all kinds of experiments are being performed.. one of which could have something to do with the creation of Ice-9.. and the game ends with Alice, perhaps the only survivor, being frozen and carried through a desert for some reason.. she is eventually discovered by someone, and because of her appearance, rumors begins to spread about a frozen egyptian princess.. even though she might be nothing of the sort.. another idea is that the game takes place at the same time as the second Nonary Game and also takes place in a lab somewhere in the desert. Eventually Alice (and presumably the main characters of this game) escapes this lab and stumbles upon a car driving towards them...

I really like that idea, it's neat. We all assumed the game is about Santa's/June's plan but maybe it isnt? What if this takes place around the same time, or in some alternate future? I read Sigma is meant to be a college student like Junpei (he looks older though)?
