When asked about the length of the latest iteration of the Ratchet & Clank series, Bryan Intihar replied:

"It’s hard to talk # of hours when the game is still in development, but I can say that this game will have a lot of replay value in comparison to ToD and Q4B."

Suggesting that the new game will include some sort of online or multiplayer mode. Insomniac surprised everyone with a fantastic Co-op mode in Resistance 2, are they looking to do the same with Ratchet & Clank: A Crack In Time?

The release date for the game is still Fall 2009, but Insomniac have said that they will be revealing a firmer release date soon, which most likely means at gamescom in August. Look forward to hearing more about this fantastic game then.
