yeah that game is one of the reasons I bought a ps4. Honestly there isn't alot of info on it, sony just stated its coming this year, when before it was a launch title, then launch window/spring, now just 2014..
I'm worried they'll wait too long to release it, and I'll have other things I'd rather play. If Sony pulled a "it's out now!" type deal at E3 for it, I'd be psyched. Summer is the perfect time for this game, as I'll be growing tired of most all my other shooters.
