Out of everything I've seen so far, that looks most interesting. Just hope it comes over to PC. I can't justify buying a PS4 no matter how good it is.
Most of it should, the architectures are so similar to that of a PC that there's minimal work involved in porting. Even better, the PS4 probably uses OpenGL instead of DirectX, so the Linux/Mac gaming scene could explode. Valve knows what's up.
I wouldn't count Microsoft out yet, you only have to look at the popularity of the Wii to see that launching with loads of hardcore games doesn't make or break a console. It's a something for everyone type of console, kid's love the Kinect games, parents will appreciate the media streaming and Satellite/Cable box integration. It'll sell like hot cakes so every game that comes out will be multiplatform and availalble on both. PS4 has a small price difference and appeals more to avid gamers who care about lower second hand games prices and offline play, but for the bulk of people the Xbox One will look like more bang for the buck.
