Looks into Vita for 2013 ..

In addition to the titles that I've listed out in a previous post (see below)

Vita 2013 - Unofficial List

The following titles have been strongly rumored/confirmed for the Vita in 2013:

Velocity Ultra - this is the rumored remake of the PSP mini release with enhancements.  New art and now running at Vita's native resolution.  Add in trophies and leader-boards.

Just Add Water - conversations back and forth with a NeoGAF user (works at JAW) about the success of Stranger's Wrath Vita has led to the revelation of 3 additional Vita titles being developed.  Some are known.  One being Munch's Odyssey.  The second title is New 'n' Tasty!  The third title is a mystery but two hints were given.  It's not Gravity Crash and it's about 60 MB in file size.

Wake Up Club - finally announced for release in the US!

Laughing Jackal - maker of Hungry Giraffe announced 3 additional titles for the Vita.  This includes a "Mystery Game X".  The current PSM titles made by them are Hungry Giraffe, OMG-Z, and Cubixx.

MotoGP 2013 - game from the makers of Motocross (MUD) and WRC releasing this year.

Final Fantasy X - Square Enix has promised news "soon" on the PS3/Vita release of this remake.  This would lead me to believe that 2013 might be the target year of release.
