Right, so TGS is going on right now and some newly relased information about 3DDD just came out:
1.) Based on a promotion poster, the game is staled to have a plan relased by Spring 2012. 
2.) Again poster, Sora and Riku now have new cloths and Riku's hair is shorter.
3.) There now this blue dog and this bat thing, again poster.
4.) Based on information collected by people over at Siliconera who manage to play the demo for the game, Neku from The World End With You is in the game. 
So thoughts so far? Also people, this should be noted, do not make a Neku page until we have gameplay or image of him.
