I think that right around $6500 is the median price for a NIB game that people are going to want. The Stern LE editions will be $7500 plus and the premium editions will be street priced at $6500 before the fall. If the amount of disparity between the LE/premium editions compared with the pro editions continues, the lowest end machines will barely hold their value which can be seen now (except for Tron). The world of the $6500 NIB machine standard is right around the corner and I don't see the prices going down one bit especially with the pre-order fun happening right now.
I think there will be even more demand for Star Trek. In fact, I can only imagine the kind of jockey'ng, kick-backs, greased palms happening right now so people have a precious LE game when the music stops at any price.
Greed is in full bloom. Gordon Gecko would be proud.
