Apparently (haven't played it), it's story is the same, but the game play is better (good thing, because the game needed to improve to be an average game).Chain of Memories was released on the GBA, and of course the PS2 remake version would be "better than the original" because the PS2 has many more advanced capabilities. And since it was remade, of course CoM was improved for more fluid gameplay and story-telling.
So, the only real game were Sora had a chance to get in from is no longer a console exclusive and has achieved more success, critically, commercially, and fan-opinions on the PS2, a system he's commonly associated with. You have to admit, that's a big dent right there for his chances.
