Does anyone think that the graphics will really be that good?
I mean, a DS can't really hold much in each game, and since Kingdom Hearts games are normally quite long, it might be too big for the DS to have good graphics to go with it (not much can be held on that little cartridge compared to a disc).
What do you guys think?

Well, looking at the graphics for other games such as Dynasty Warriors... or a better example, Final Fantasy, the graphics really aren't that pretty. It's classic Nintendo; they make cartoony games. It's what they're used to, and what they're good at.

I'm thinking the graphics seen are probably from a PC re-make, ust to show off and make people want to buy the game, then be disappointed.

if you go on youtube and look up KH:358/2 days leaked footage you can get a general idea of the graphics. From what I saw dont expect it to be as good as the psp version i'd say it's around CoM's graphics.

... except that the graphics are supposed to be 3D instead of 2D.

well the gameboy graphics were pretty good at the beginning so this should be better
