nobody will buy the new lair pack

^ I think its free

hmm, if the MS 2 trailer we saw last week is released on March 20th on the PS store then I'll be convinced.

Yeah, the MotorStorm 2 trailer should be the sign.

That trailer should look so awesome on my HDTV. *drools*

Looks like a good line up anyway :D Hope the new KZ2 trailer shows some new stuff! If this is to be believed anyway...

Despite it being CGI, watching the Motorstorm 2 trailer made me relive moments of the first one playing as a biker and making some pretty painful splats on the ground.

Since the other thread about this lost out to this one, I'll ask again:

"What is Ratchet Quest for booty (bottom of spreadsheet)?"

Haven't you heard, it's Insoniac's take on the adult industry! :P

If I had to guess (if that could be a real game) is that it'd be some story taking place after Tools of Destruction becase in TOD  you kill an evil robot pirate, which automatically makes Ratchet the pirate's new captain.

R2,ican't wait for the trailer
