I was at my local Game Crazy picking up Contra 4 in all it's manly goodness and I spotted this on the wall.
One of the guys, Jim, posed for the picture that I took as proof that the game was indeed in.
I've really only played the demo, I did not have the proper funds to pick up Contra 4 AND a PS3 game but the demo was surprisingly solid. I do believe if you are hurting for a PS3 game right now (and honestly, who owns a PS3 and is NOT hurting for a new game) and if the rest of the game is remotely like the demo, you really can't go wrong with it.
It felt like a bastard child of Indiana Jones, Tomb Raider, and Gears of War. With 100% less whips though.
