According to an article at http://www.gamerspress.com/article.php?sid=2167 Steel Batallion appears to selling out.
Here's the article:
"We just got off the phone with our Capcom PR rep Mr. Atwood - looks like the company is *very* excited at how well the game has been recieved (and shown on the Today Show, Popular Mechanics, and everywhere else). He mentioned that there should be another shipment of the game/controllers before Christmas, and that the company was set to produce as many units as it takes to fulfill customers demands. So don't waste your money on Ebay just yet. ."
Pretty cool stuff considering it costs $200.
