Killzone Vita trailer
Ghost Recon Final Mission announced (this got leaked with AC3 way back)
Invizimals Vita announced
Gran Turismo Vita announced, only showing the logo
The reason why I put the games in the above list
Gran Turismo is most popular in Europe
FIFA is extremely popular in Europe, if they showcase cross online play and being able to continue master league through cloud save, this would be huge
Invizimals was quite big in Europe for PSP, a Vita follow up makes sense due to the extra AR features, also the last game the developer made was Reality Fighters
It's time to see gameplay footage for COD and Need for Speed, both games are coming this year
Ghost Recon Final Mission was leaked along with Assassins Creed 3 Vita here is the
link
MediaMolecule and both Guerilla Games are rumored to be making a new IP, I am guessing one will show up
Quantic Dream are European developers so it makes sense for them to show of more of Beyond, plus we still haven't seen enough of it unlike LoU and GoW4
