GTA4 has been a big let down for most of the people I've spoken to, I really can't see many people caring about this by the end of the year/early next year
I think its a good move. As has been said, everyone will not be playing GTA IV in November, along comes some new content to get people back interested.
I haven't touched it since completing it. I'm not even sure if I actually did complete it or if I have one more mission to do. I simply don't care.
All the other GTAs i've mucked about on way after completing.
