Nope, these seem to be legit US versions. I got this picture from one guy's auction.
The seller's name is "discount_electronics_surplus"... which may mean they got the game on clearance or something.
Edit: Yeah, many of his items appear to be stuff fished out from the returns bin or Goodwill. I think this guy got a ton of Best Buy's returns / trash items and decided to sell 'em online.
