MGS5 (not V, 5) is probably going to be released on PS3. Now that most expensive work (engine and basics) have been done already, I doubt they have any need for more money than they will get on PS3. Also, at the time of MGS5's release, there will be a lot more PS3s. No, definitely not coming to X360 unless it somehow flops, which would actually mean it's a bad game. Next-gen MGS? Too early to say. I'm pretty sure Kojima is trying to end the series already but I can't really say much without playing MGS4 and MGS5. I'm afraid he'll be starting it again in MGS5... I think it's really time for an end already before the whole series gets somehow ruined by Konami.
FFXIV might also be coming this gen. They will stick with PS3 unless FFXIII fails. X360 isn't going to save them in Japan so it's not their hope in Japan either. As for the rest of the world... I think PS3 is enough for FFXIII and they'll stick with PS3 in the future as well. Next-gen FF, however, could be a very different story.
Next GTA might well be PS3 exclusive due to PS3's success and Blu-ray. Next-gen GTA, however, is probably going to be multiplatform.
The more I type, the more I realize the next generation is very worrying indeed. The only exclusives are going to be 1st party as it's going to become too expensive to develop good games on a single platform. It's very expensive even now. I think we might be going to see some huge deals. I wouldn't be surprised to see Sony tightening their relation with SE.
EDIT: GT, not GTA? I'd better learn to read. No, definitely. There's no way they would release it on X360. Sony will buy them if they even think about it (if they really haven't yet). No, no and once again no. Besides, GT series has always sold very vell on Sony systems. One of the most succesful exclusives it seems.
