For those who don't know someone at Neogaf created a list of rumors and so far everything in that list seems to be falling into place.
Here is the list:
[ ] 4 Warriors of Light 2, 3DS
[x] Monster Hunter Tri G, 3DS
[ ] Miku Hatsune (SD style), 3DS
[ ] New Shining game using Valkyria systems and characters from Shining Hearts, PSP
[x] Sega has a Layton-like game but with rhythm action instead of puzzles, to be announced at TGS.
[ ] Bayonetta 2 is in development and is planned for release at the same time as a theatrical Bayonetta CG movie.
[ ] Vita launch later this year, Monster Hunter 3rd HD will be announced at TGS to be a launch title.
[x] DQ10 is being designed as an MMO-like game.
[ ] Persona 2 Eternal Punishment PSP, November 2 release.

I am personally interested in a Shining Hearts game using the Valkyria system (most likely won't make it over, but still interesting).
