When the fuck did people start taking HHG seriously? "He practically works for Sony" pffft. When I was a mod I used to lock all HHG threads at first sight.
Anywho, it's my understanding that Sucker Punch is working on a new IP, and I'd assume both that and Uncharted 4 are aimed for ps4's launch, with the Last of Us being Naughty Dog's last big game on ps3.
