just picked up my copy at the best buy in yorba linda, ca. they have 2 copies of the ps3 version on the floor as well as 3-4 copies of the xbox 360 version in a cage. both were marked $19.99, but may ring up at $9.99.
played through the first 2 levels. pretty much a poor man's god of war, but really not as bad as the demo made it out to be.
