While it’s known that Insomniac is working on a multiplatform game for Electronic Arts, the developer indicated it would still work on PS3 exclusive projects. Sure enough, the company has announced that they will unveil their next PS3 title at PAX 2010.

“We’re bringing our new game to a very special Penny Arcade Expo panel on Saturday evening (September 4), at 6:30 p.m. in the Serpent Theatre,” wrote Insomniac in a newsletter. “G4TV’s Adam Sessler will moderate a panel with key creative talent from Insomniac Games as we discuss (and demo!) our upcoming PlayStation 3 project.”

It surprised many that Resistance 3 was not shown off at E3 2010, considering a billboard for the game was seen on the set of Battle: Los Angeles. Given the timing, it seems highly likely that Resistance 3 will be the title that Insomniac will announce.
