This is an announcement announcing the announcement of the announcement of a new game from Insomniac. The Ratchet and Clank makers are preparing to reveal a new title some time between now and PAX Prime on Labor Day weekend.
We have no more information than that, although if you want to be among the first people to check out the trailer for Insomniac's incredible-mystery-OMG-what-is-it?? game, the move is to subscribe to their newsletter. They promise they'll be sending out a video of the game to newsletter subscribers the moment it's announced at PAX. We'll have the vid up at G4 soon after that, trust me.
Even better: If you're going to be at PAX in Seattle, attend Insomniac's panel on Saturday evening (September 4), at 6:30pm in the Serpent Theatre. Where X-Play's own Adam Sessler will moderate a panel with key creative talent from Insomniac Games. Whatever the new game is will be shown, and demoed, to the adoring crowd at Penny Arcade's Expo.
