Why should you see more of an item that has not yet released based on qty alone? You cant judge qty of supply based on what is on ebay.
I seriously doubt RE quad is 3k,(I guess I could confirm....) if one person is advertising it as 3k, then its because another retailer/etailer got 1k. There are very strict MOQs in place and while they make an exception here and there ... I see no special circumstance to prove why they would have allowed 3k for RE.
Almost seems you are a little too proud to own RE4

, I mean what are you trying to say? ... Maybe you dont see alot because all the people who wanted it ... bought it. Its pretty obvious what will be a more popular resell of an item. RE vs. Iron Man .... IM will win all day. REtrilogy from Korea even looks better and is 10x harder to find than the REquad ...
RE quad was available on another German site, I cant remember which one, but it was sold there and then resellers sold it on amazon.de ; I dont know the whole story on the title as I already own the individual steels so I wasnt initerested but perhaps these also appeared in some brick and mortar stores in Germany.
