With online sales 3DS/WiiU Smash may be the best selling Smash already but this week it will be counting only retail. 3DS version total sales were over 2M 1-2 weeks ago, it will outsell Brawl not long after holidays.
That's one of the most unexpected results of the year, really. SSB for 3DS was always going to be a hit, but so big...?
Level 5 has shipped more than 2M for Shin Uchi. There weren't supply problems at launch, there won't be supply problems this week.
MC has a shipment of about 1,4m units. Perhaps 2m includes also the following week?
