Pretty sure I'm gonna go to my local GameStop today and switch out my PS4 preorder to an X1. I currently have a PS3 since I sold my 360 last year because I didn't need two consoles. The thing is, I never really fell in love with my PS3 the way I did my 360. Bad decision.
I initially bought into the hype with the PS4, but later realized all of the innovation Microsoft is bringing to the table is actually pretty neat. Another deciding factor is the fact that I'm not really a fan of any of the PS4 launch titles, nor Sony's exclusives (sorry TLoU, but you'll always have a place in my heart). I don't think I've ever been more unexcited for a game I've preordered as I am now with Killzone 4. Titanfall had me wowed since the reveal and Forza imo is the best racing sim available. I recently popped in GT5 and couldn't bare to play it for more than five minutes; it was just so bland and unexciting.
Other than the $100 difference between the two consoles, I don't think there is too much of a reason for me to go ahead and purchase the PS4. Seriously, how much better are the graphics going to be on the PS4? With all the things Microsoft is going to implement with their cloud tech, I only see that gap closing in the near future.
