Those who've been aware of some the latest news regarding Ratchet & Clank: Tools of Destruction, should know that a demo was created and finalised for atleast a month now. Angry calls have been based on asking Sony to release the demo such was the lack of new entertainment on the system; however the Senior PR Manager on the Sony Blog has confirmed that the demo will actually launch close to the release date of the game.
As the game is scheduled to be released on October 27th, it's likely we will not see it for atleast another month.
