Wow... I knew it was valuable but it would actually resell for more than the original? That's amazing news....
But it might be wishful thinking. We never get the speciality stuff here. Nobody has ever heard of a 360 Elite here and there's no such thing as a 20GB PS3 (so say the dealers).
Well, one would assume it would eventually sell higher. Taking into account that moat (if not all) limited edition systems do. The pickachu N64 sells for quite a bit more than a standard in the same condition. And then you have the top loading 8-Bit Nintendo (which I am a proud owner of one) sells for nearly $120 today if its still shrink wrapped, compare that to the $20 or so the standard front loaders go for, its certainly worth the extra $50 investment for a halo themed 360 IMHO.
