See that boxart in that Resistance 3 listing. Notice anything familar?
eStarland has the Insomniac sequel listed on its website for a March 24, 2011 release.
But the kicker is the boxart. It shows off a direct-feed image of the logo that was shown on a billboard last September. The same one that hugely hinted at the game being set in New York.
Sony has yet to formally announce the game, let alone release any assets like the logo, so make of this as you will.
Until now, nothing has come up on Resistance 3 since before developer Insomniac Games announced it had signed a multi-platform deal with EA Partners: back in March, the game was mentioned in a survey.
gamescom? Don't rule it out. We'll drop an email to SCEE.
