Kingdom Hearts 3D: Dream Drop Distance Trailer (12-20-2011) [Update: 8 minute full trailer]
So we got the main cast of characters from The World Ends With You with voice acting, Sora and Riku get new duds, Disney worlds some new and some old, Terranort, old man Spock~ I man Xehanort, Axel saying his real name, and mother freaking RINZLER from Tron Legacy.
I am sold on the content and presentation, if the story is bogus.. well that just comes with the KH territory. All that's left is actual gameplay. If it impresses then I might MIGHT just get a 3DS. Maybe.
