It's compatible with the Dual Shock 4. It's just that this launches in Japan in November, but the PS4 doesn't come out until Feb 2014.
A fair few of the reasons, particularly the output resolution being 720p/1080i are disappointing though I agree.
I'll probably get one for shits and giggles as £70ish is small change really and I'd love to enjoy the audio on some of the games like Soul Sacrifice on my home theatre setup. Though I don't see the bigger image doing the visuals much justice.
