I'm guessing they have Mk I stock still and want to get rid of it. If they just ship the Mk I units they have when people order the MFC, they might end up with a few complaints from people expecting to get the Mk II. If they just priced the two versions the same though... really, who's going to order the Mk I? Even if you have no intention of using the Ethercon connection, you'd still go for the Mk II if the prices were the same. So I'm guessing there's a price discrepancy until the Mk I stock is cleared out and then the Mk II price will drop back down to the usual.
