IDK I'm an xbox fan, even used to play halo competitively. Never owned a PS3. I'm getting PS4 for Killzone (never played any previous KZ games before, but it looks pretty cool) and BF4. The xbox one was always in the cards for me I was just pissed about the specs/raw power compared to the PS4 and having to buy with Kinect. I really want to play Forza on launch
I personally cannot justify buying the ONE but that's me.
I am paying 100 more for a console that comes bundled with weaker specs and a camera...
I mean, I understand you are in it for the exclusives but I think I can assure you you're gonna like the Sony 1st parties as much as you liked MS's.
The ONE price is bound to drop by a 100 soon enough so I'd just wait it out if you want to buy the ONE at a later time.
By then, you should know better anyway.
