I would much rather have it on the PS3. Why? Well because in my opinion it just suits it. I can go back and play Kingdom Hearts on my PS3 and I could go back and play Kingdom Hearts 2 on my PS3, and if KH3 arrives on the PS3, I can play all of them on the PS3.lol Its like having the story unfold right before your eyes all over again.lol I just recently started a new Kingdom Hearts file on my PS3 and it runs nicely.
If Final Mix+ arrives outside Japan(hopefully) then I will have the entire collection and they will all be playable on the PS3. Its just traditional, I think since the PS3's controller function has not changed much, the controls of the next Kingdom Hearts game would play flawlessly and they could create a more complexed battle system with easier controlls. Just imagine what the Cell Processor could make KH3 look like, the AI would be perfect and since the PS3 is good with tasks, just imagine how many enemies could appear on screen at once without any feedback!
