Its just an after Christmas sales deal, EB just wants to move the stock that didnt sell over Christmas. Wii's are still in demand down here (try find a red Wii in an EB store here) calling it an upgrade is just them using a sales tactic to get you to buy something you don't want.
Some people are taking this way to personally, Id hate to think what they would say if they saw there favorite console in a pawnbroker, bargain bin or worst of all a garage sale!
