once again a proper list of all the Sony studio are working on

[eFKac]

I believe Yoshida stated they have 30 games in developement in WWS, 20 to release during PS4's first year on the market, 12 new IPs and that would coincide with that list when you cross out studios that are not first party. He may be counting SOE as a part of WWS now. They also may be counting the independent dev studios who collaborate with XDev and are published by SCE.

Anyway great list, some projects to be announced that I am extremely eager to find out, namely ND game for PS4, Stig Asmussen's new IP, and Media Molecule's new game (very probable to be shown on Gamescom I believe).
