Games this gen and last take longer to develop than during ps2 era
With that said they milking the hell outta gta online, which is a double edge sword for gamers
They'll be announcing a new red dead sometime soon though that seems like the logical next game for them
No, they really dont, this gen is based on x86 where as previous machines were all proprietary architectures that were difficult to develop for by comparison.
GTA 4 came out and a 2 years later Red Dead Redemption came out, we're going on year 3 since Rockstar released anything and the reason is pretty simple, GTA5 online is a cash cow. They had been on a pretty regular schedule with their games, garbage ass L.A. Noire came out before GTA 5.
