By the way, from what I gather, the reason LRG couldn't cap purchases on this one is because they're selling it on behalf of the publisher, whereas normally the CE is driven more by LRG themselves so it's "their" product that they've merely licensed (like the French company that obtained permission from Sega to make a Shenmue I & II CE last year).
Obviously the Dreamcast case, trading card, and box sleeve are LRG-produced enhancements, but the base product is still Deep Silver's, whose accountants will expect it to be sold as keenly as any other version - you don't see Amazon or GAME limiting sales to one per customer, regardless of stock levels.
