Never trade in a console. You'll always regret it. Barring exceptions like the Virtual Boy, of course.
Just save up for the Wii or DS, so you can have them in addition to your other consoles.
Inevitably, there will be moments that you regretted selling your console. You may miss playing LBP. You may want to replay MGS4. You may want to pickup Uncharted 2, but can't. It'll happen, and you'll be kicking yourself.
For the $150 you'll get at GameStop, or the $250 you'll get on Ebay, it's just not worth it.
