This prrrrobably will happen, regardless of whether it's a good idea or not. We're talking about Capcom here, the people who have been ruining franchises with inane sequels since gaming began. Basically if they think it'll make money, they'll do it, with or without the blessing of the original designer/artist/whatever.
I don't remember who said it, but GS is far from a niche title, at least in Japan. It's actually one of the best-selling franchises, and considering how cheap it is to make it, that means it'll be around for a while. It's very possible that we'll see a Wii remake of a GS game (or maybe even a new GS game), but that it won't be localized to English. I'm not quite sure of the popularity of AA in the West, although I think it's pretty good too.
Personally, I don't think I'd be interested in playing an AA game on the Wii if there's English voice acting in place for all dialogs. That would just ruin the mood for me, especially considering the average quality of Western anime voice acting. Also, to me AA interface is absolutely perfect on the DS. Honestly, I can't think of another DS game with a better interface, save maybe Meteos. While you could make the interface work the same way on the Wii, I think it'd be much more of a pain to play.
But high res art like in the TGS 05/06 cases would definitely be cool!
). Plus, voice acting! I also love that they kept the original GBA-quality music.
