Sony's French PR have just sent out a press release revealing Ratchet and Clank: A Crack in Time.  Crack in Time takes place shortly after Tools of Destruction and Quest for Booty, and will see Ratchet travelling through time to rescue Clank.

The Ratchet and Clank franchise is multi-million selling series, spanning the PS2 and PS3.  Tools of Destruction was released in 2007 and was a huge critical and commercial success, selling more than a million copies. 

Ratchet and Clank: A Crank in Time is an adventure game developed by Insomniac Games. The title is due out in Fall 2009, exclusively on PS3.
