Wow, I have to say I'm shocked to discover that leo-j was right. However, can you blame me for wondering why the hell scans of a PSP game weren't in 16:9??? It still makes no sense. I guess that means what we've seen so far isn't the actual graphics of the game.
Anyway, other than the cell phone game I get both! That's why I like having both handhelds. My PSP is starting to slowly become worth more than just a portable rom machine. The DS one sounds more interesting to me though. 4 player co-op? Online maybe? Also, IGN said it seems really dark.
So, it appears that this story http://www.joystiq.com/2007/05/04/next-kingdom-hearts-to-be-portable-spin-off-not-khiii/ was about the DS game. That means the plot we are can look forward to for the DS game is what happened to Mickey in the World of Darkness. Very cool.
