Common guys, stop fighting about this stupid FFVII remake... I think all of you got some kind of a point.
The Wii and the PSP have more or less the same userbase at the moment, so you can't say where the money really is. Of course, the Wii's base is only growing and until such a game would be released, it would be quite a bit more than it is now, but on the other hand, WoW has a point with the "better fitting lineup" on the PSP, though this is not about artistic style or anything, but more about a userbase highly interested in a FFVII remake.
So the Wii seems to be the console with more potential, but also more risk. Also, a FFVII remake would probably move consoles anyway, so it doesn't matter too much on which console you put it. However, as most of you said already, we are probably far away of such a remake anyway since Square has enough other things to milk currently, so please do all stop arguing since you're going nowhere anyways.
On topic, I think RE and GTA spinoffs are a given, and Konami will also put some kind of Castlevania on the Wii sooner or later (apart from Judgement I mean.) Square Enix is probably going big with FFCC now that they see how the Wii is selling, so I expect this to be great. We also have DQX from them, so they are more or less settled for now. It would still be nice though to see KH and Mana, but as others have said, Mana needs to be newly invented, or, even better, brought back to the roots.
