Pre-ordered my PS4 and a copy of Killzone: Shadow Fall back when they first came up on Amazon. I've got a high-end gaming PC alongside that, so I'm thinking I'll be perfectly content on ditching Microsoft this time around.
Even looking at my 360, most of the games on there were available on PC. If it weren't for Cave shmups, I'd only have a handful of games that make it worth keeping that I can't get elsewhere.
