Bit of a story to help you understand my situation.
I've been a gold member for about half a decade. After awhile I got a PS3 when it got cheaper after many exclusive titles have been building up over the years. That said and done I have played the exclusive titles I want and I let my gold membership expire. My situation is that anything short of a AAA online exclusive game I would just get it on the PS3. I prefer the 360 due to a cleaner and faster online not to mention a more sophisticated controller but there are many times where I had membership and only played offline games before. As people get older then make better money choices. If Gears of War 3 wasn't an exclusive I would buy it for the PS3. But seeing how it is an exclusive that I consider AAA then I would be willing to renew my gold membership. But in the long run, just giving my prospective where the xbox 360 stands.
