Sorry but im with the other guy. I could care less which system KH came out on. If it's PS3 then its PS3. 360, Revolution, heck even the PC. As long as its the same people working on it then i know it will be the same quality work i expect from Square-Enix.
Please people dont buy into video game biases. There are so many good games out there that arent played because so many people think one console system is evil because it is made by Bill Gates, or kiddy because it is on nintendo, or a sell out because it is on Play Station. That line of thought will eventually destroy video gaming as a hobby and its one of the reasons why it gets no respect as an art form.
The only reason Xbox 360 didnt do well on its japanese release was because the japanese titles Like DOA4, 99Knights, and the Mystwalker games (which are made by the original creator of Final Fantasy) were not release day planned titles. When DOA was finally released the 360 sold almost double what it did in its first few weeks.
And if square enix did just happen to move to xbox, even though i think they wont, it would only make Japanese gamers reconsider the Xbox as a gaming machine. Some hard core people (like most people on these forums) will never forgive square and never play their games again but that means they will only miss out on the amazing games that square enix put out. Just like nintendo fans who condemed square for going to playstation.
Moral of the story. Final fantasy is Final Fantasy. Kingdom Hearts is Kingdom Hearts. Square-Enix is Square-Enix. As long as its the same people. Then it is the same good games. Games make the console, not the other way around.
