Ahem.
After they made Kingdom Hearts 1, they made Kingdom Hearts 1.5 (Chain of Memories), They put it on the Gameboy Advance. Now, after KH2, If they make a KH2.5 (If there's going to be a KH3, I honestly wouldnt know), It would be logical to put it on the PSP.
Now, for all those people saying that the PSP doesn't have enough buttons, It Does. As somebody already said (Kudos To Them) the PSP has more buttons than the GBA, so stop complaining.
