Apparently, GameStop has a deal where you can trade in your ‘fat’ PS3 for $150 towards the purchase of the new slim PS3. All you need to do is supply everything that came with the system (minus the ethernet cable), and you’re golden. This is a for-sure deal for 40, 60 and 80GB models. No definitive word on the 20GB model, though most GameStops would probably honor it. You can also get $50 toward a purchase of a slim PS3 with a slim PS2, two controllers and a memory card, netting a possible total of $200 toward your purchase. For those with a 60GB, would you be willing to part ways with the system’s extra features, including backwards compatibility, just to get the new model? Source
