I'm wondering if they'll release it in 1080p first then 4k later, I'd imagine Sony want to push the "Pro" model so probably 4k from the start.
The cynic in me thinks 1080p, then pc announced closer to release) with NO Pro or Xbox Scoprio support, followed by a 4k version months later (sarcasm)
The multiplayer is almost guaranteed to have Rockstars real digital currency - the stuff you buy, to purchase extortionate digital / dlc goods in game
