Kingdom Hearts: Chain of Memories for PS2!

I always wanted to Kingdom Hearts: Chain of Memories on the Gameboy but I never had a Gameboy. Just found out they are remaking it for the PS2! It will be $29 so I'm thinking it will shorter than a PS2 game and probably more the length of a Gameboy game. :/ Anyone have any more info?

I think there's a thread for this already.
