After yesterday's teaser image posted by Sony, I saw people speculation from everything to a new IP, to a possible correlation between November 3rd's hybrid solar eclipse and the release date for the PS4. That's all wrong, though, as another teaser image was posted via Twitter today with an @InsomniacGames mention along with the link to the image above. Note the mention of "heroes" making a "return".
If that wasn't enough for you, someone managed to snap a screenshot (above) on their PlayStation Vita showing a PSN user playing a game called Ratchet and Clank: Into the Nexus. Later, another image surfaced showing yet another user, an Insomniac Games community PSN account, playing the same game.
Another Ratchet and Clank title is all but confirmed, and all that's left is to find out of the game will release on the PS3, the PS Vita, the PS4, or some sort of combination of the three. We'll update or create a new post when the information is made official.
