Yesterday, Sony teased a new game with a mysterious picture which said "When Worlds Collide." Today, Insomniac Games posted an updated version of the picture on its Twitter and Facebook pages, saying, "Big News coming tomorrow!!!!"
N4G user Wizziokid noticed the image appears to resemble a Rift Gate from Jak & Daxter: The Precursor Legacy and Jak II. This, combined with the poster's suggestive wording, could be hinting at a Ratchet & Clank / Jak & Daxter crossover title.
Then again, it could be a proper sequel in the main Ratchet & Clank series. NeoGaf users 8byte and ixYi spotted PlayStation Network accounts playing an unannounced game titled "Ratchet & Clank: Into the Nexus."
Stay glued to PSU for updates on Insomniac's new project as the story develops.
