Ratchet and Clank

Im a fan of the Ratchet and Clank series and I was wondering if anyone had any info or insight on what to expect on their newest installment Up Your Arsenal. I saw a couple of things about it and read that they will have multiplayer online which will surely be fun. Can anyone give me any more info?

New weapons, new bad guys, more customization for your ship, ect. I thought the first and second games rocked, so the third should be no different.
