Gears of War going multi-plat wouldn't be surprising at all, really. At the very least, I'm certain Epic is making a multi-platform game, or else Mark Rein wouldn't have looked so ecstatic over the 8GB of RAM announcement.
An old property wouldn't surprise me, either, and I still have my suspicions about Crash. He's featured very prominently in PS4 advertising. Ordinarily you wouldn't do that with a lost IP.
The price is where I have trouble believing. Not only is it too low but I also doubt that it's been set yet, not 8 months away from launch.
