Lol at a week, try 6 months possibly for PC and maybe the same if not like a year for next egn ( if not also released on release)
6 months? I hope you aren't basing that on GTA IV which was a first-time development training thing for one of their studios. Max Payne 3 was out a month later and was a really, really solid release in technical terms. They obviously spent a lot of resources in training up people to work with the RAGE engine on PC, I'm fairly certain we will see a solid and quick PC release.
