I place emphasis on being able to game with friends, and I know about 2 people with PS4s compared to 10+ people with Xbox One - it was a no-brainer. Exclusives, I can take the trade-offs and would be happy with either library of exclusives. My most anticipated game is multiplat anyway - Destiny.
Xbox one now for current games, ps4 in a few years with a price drop and maybe better exclusive games by then. Don't buy a ps4 for not noticeably better graphics over the system you would play more thanks to better exclusives.
