Personally, I want KH3 on the PS3. What do you guys think?

I think it is a given that it will be on PS3.

 

I would personally prefer it to be multi-console. Why? 'Cause I don't have a PS3. I count that as a valid reason, since I'd be willing to bet that everyone who says it should be on (especially if they said exclusive to) PS3 either has or wants a PS3. Do I have other reasons? Sure:

• Having the game on more consoles automatically makes it available to a wider audience.
• Just because KHIII is supposedly going to be using FFv13's engine, does not mean that other consoles will be not be able to handle it. Even if the PS3's current contenders wouldn't be able to handle it, the Wii U is coming out soon. I don't care what rumor you read, or how much you think Nintendo's consoles suck, Wii U is not going to be weaker than the PS3. That would literally be suicide. No matter the mistakes Nintendo has made, they are not that stupid as to release new hardware weaker than a competitor's hardware that has been out for years.
• Just because KH I and II were on PS2, doesn't mean that KHIII will be on PS3. Going by that logic, Final Fantasy would never have gone to Sony consoles. I could think of more examples, but since KH and FF are made by the same company, I figure this one is good enough.

I have other reasons, but they are more issues I have with Sony than anything else.
