Syphon Filter 5 and SOCOM 4 are in development currently according to digital content creation company PCB Productions as listed on their web-site.
As far as Syphon Filter 5 is concerned the game is apparently in development by Sony’s Bend studio and PCB Productions will be providing the facial motion capture that the animators will be using in the game to make it more realistic.
SOCOM 4 is mentioned as in development but no information on the game is revealed, and neither title has officially been announced at this point.
Along what PCB has done includes content for Bioshock, development on most of the Call of Duty games, development on Ghost Recon Advanced Warfighter 1 and 2 and other big titles.
Neither of these titles would be a surprise if announced, but take the news with a grain of salt for now.
