Those screens look nice, especially the one in the town vs the giant heartless. Co-op sounds really cool... i hope in single player you can switch control to any character -- that would be fun.
on the other hand, the screenshots on the top page of those scans look like the DS will suffer even worse from the "trapped in a box" feel of the PS2 games. What i mean is that many areas in the PS2 games were very clearly just boxes with backgrounds painted on the walls... they didn't fake open spaces too well.
Also: let's hope the framerate is decent -- there's a lot going on in those shots!
