Outside of Uncharted: Drake's Fortune coming next month, this is the game that will most likely be the Playstation 3 Game of the Year. This is the next game in a proven great franchise and Insomniac would have to really screw things up in order to not make a good Ratchet and Clank game.
It is a sad state of affairs that Sony's best games are coming out so late in the year for the Playstation 3. I don't think this game is going to spur sales in any way, but it should be a really good game and probably the best game so far for the system.
Other games this week include:
Eye of Judgement (Sony, PS3) - will be reviewing once copy is here
EA Playground (EA, Wii/DS) - looks fun with a lot of sports games
Ace Combat 6: Fires of Liberation (Bandai Namco, 360) - some people swear by this game and there is even a controller to go along with it
Castlevania: The Dracula X Chronicles (Konami, PSP) - must get if you have a PSP. Rondo of Blood in 3D and 2D as well as Symphony of the Night included
Naruto: Clash of the Ninja Revolution (Tomy, Wii) - sounds like a good fighting game for the Wii
Phoenix Wright: Ace Attorney Trails and Tribulations (Capcom, DS) - many people love this series, so why not pick up the new one?
Zack and Wiki: Quest for Barbaros' Treasure (Capcom, Wii) - good word of mouth so far on this one
Painkiller: Overdose (Dreamcatcher, PC) - a mod that turns into a full game
