See...that's exactly the thing I was trying to point out. The only way they could hope to make a worthwhile profit on something like this would be to sell them for $100. It's not like factories are still manufacturing SNES games.
Everything else you said is completely valid. I really don't know who the market is...other than what gbpxl said. They must think they can sell at least 4500 though. About the ONLY thing that makes sense to me is the cost.
