Metal gear Solid HD game comin and Legend of Heroes and Phantasy Star Online 2 and Persona: The Golden and also..a Gundam lookin game. If you scroll down on the Vid theres more vids showing each game. Also, some kind of UMD Passport system, i guess to transfer over UMD stuff which im sure we'll never get.
It will be possible to play PS Vita version on the same server as the PC version and, according to Sakai, it will use "exactly the same data". Thus, players can take their PC characters and play them on the PS Vita. The PS Vita version of Phantasy Star Online 2 is slated for a 2013 release.
Sony has announced a 28th June release date for the Vita version of Metal Gear Solid HD in Japan.
Also spotted in the video: Super Robot Wars, Gundam Mosou, and a new game from Mega Man creator Keiji Inafune.
In a video message Inafune described the mysterious Vita title as an "Inafune-like" game. It's also "amazing", but then he would say that.
Sony also announced Discovery Project, a collaboration with Japanese company Kadokawa Games.
Also, some markerless ar game demo being unveiled and others: http://www.engadget.com/2012/03/09/sony-shows-off-playstation-vitas-augmented-reality-chops-at-gdc/
I cant wait for Persona. However, an all-online MMO is a horrible idea (Phantasy Star Online 2), IMO. Theres going to be so many pervs, its going to end up like PS Home.
