The San Diego Comic-Con will feature video games from Sony PlayStation 4, PlayStation 3 and the PS Vita.  Technically this is the first time the system will be available to play publicly (since E3 is an industry event and not open to the public).  Sony is leading the charge with DriveClub, Knack and indie game Octodad: Dadliest Catch for the PlayStation 4.

Highlights for the PlayStation 3 will be Beyond Two Souls, Gran Turismo 6 and Batman: Arkham Origins.  Sony will also feature numerous panels, signings and more activity — we’ve put together a short video talking about the PlayStation events at Comic-Con – enjoy!
