You know what you want but I don't agree with what you've done. You've given up an established console with a great library for the promise of something better. I think you're going to regret it. Personally, I haven't purchased a retail PS3 game since MGS HD Collection last November but, I woun't ever get rid of it (and don't worry. I'm not hating on the PS3. Maybe 95% of the 360 games I bought this year are available on the PS3--NOBODY had great exclusives for the first 10 months of 2012).
I've been there for many console launches and there is always a bit of disappointment, a software drought, and some possible hardware issues. I'm getting a Wii U at launch because I have no willpower. But if the only way to get one was to trade a console, I would have waited. Hope you don't regret the decision.
