Sony just posted on Twitter an update of yesterday's "When Worlds Collide" teaser image, adding the wording "Heroes Return" at the bottom. You can see it above.

What's even more interesting is that the tweet including the picture was directed @insomniacgames, Insomniac Games' official Twitter account. It's pretty much easy to assume that the mysterious game isn't so mysterious anymore, as it's probably a new Ratchet & Clank. The "heroes" theme has been a regular one in the franchise, after all.

Of course it's still a rumor until we receive official confirmation, but I'd say you can pretty much get used to the idea that a new Ratchet & Clank game is coming, most probably for the PS4. I'd be really surprised if I'm wrong about this one.
