Even though I just bought a new 360 copy for $16 shipped from the EA Insider deal, I'm tempted because the CE contents are the same between versions. I think the soundtrack and art might be worth something to me, and even the crappy plasma cutter replica is a nice trinket. I could probably get at least some money for the game on top of it, right? Sadly, I doubt the in-game items are transferable to a 360 version, even if they're just code redeems.
Edit: There's no TIV back to Amazon for the vanilla game, but I'm sure you could get away with selling it for $10 new or something.
