It doesn't seem to make sense NOT to publish their games on PS3, unless someone is bribing them not to. They could have sold a few million games, and the games are 75% done, the textures, game and level design, motion capture, scripts, sounds, it's all in the can, so it's just a matter of programing a PS3 source engine port. May be not an easy task, but kind of weird that they haven't. Like I said, it's not like they are making the whole games over from scratch, for a relatively small effort they could open up a new market. Maybe they should just pay Naughty Dog to do it!
