I got my PS4 on day of release, and it's splendid...and will be even more so, when there's more than CoD, BF4 and Killzone to play on it!
I did BF4 on the PS3, and redoing it on the PS4 really shows what a step-up in graphics it is, and Killzone just looks beautiful in all aspects.
Will not be bothering with a "Cross-Bone" this time around, as frankly the last GoW (Judgement) was pants, and the Halo franchise has become a bit repetitive now. (I am seriously looking forward to "Destiny", however! Good job it's a cross-platform game...)
