Fallout game on Vita - A dream to live on, but only a dream IMHO.
a good Strategy game - Announcement of Samurai & Dragons in the West (imo not so good a game)
A big atlus game - Shin Megami Tensei IV would make me so~ happy
Some good open world game - like Gravity Rush 2?
Might or magic - hmm, IMO not feasible
Localization of many japanese only psp and vita games - ehh, would love to have it...i hate to manage between my 3 vita PSN accounts (european, american and japanese)
I also hope that it would be Gran Turismo VITA, but I won't cross my fingers, because recently i begin to be more pessimistic about vita.
IMO the new "big" title announcement will be this:
Die! Die! Die! from Polish game developer iFun4All
