Various blogs and news aggregators have been reporting that Ratchet and Clank: Future Tools of Destruction may be getting released earlier than expected, with the evidence being recently changed EBGames and amazon.com sales date (to the 23rd instead of the 30th) as well as Insomniac's recent confirmation that R&C has gone gold. We contacted Sony to get the official word, and unfortunately it looks like there is going to be no early release for Ratchet and Clank.
Jennifer Clark, the Sony PR contact for Ratchet and Clank, confirmed to PS3 Fanboy that production is complete and some copies are starting to ship out to retailers now, but that the official release date is still October 30th and won't be changing. She did mention that some a lot of stores may release the game early. So go get your Ratchet on if you can find it.
