Well, it depends how much it sold, because I'm not sure how big digital sales are for the Wii U.

Really wish we knew the actual digital sales tho....

your right, i just notice it sold more on eshop than games like SONIC RACING in just a mere 3 days! even if sonic gotten only 10k thats pretty  damn good right>>? or maybe not :(

Yeah, it is pretty good. I wish I had the money for the Wii U, because I played it at my aunt and uncle's house, and thought it was pretty fun.

i kno, 3ds is easier to tell, anything that sold more than Fire Emblem (US) means its at 100k+ but with WiiU i cant tell a thing, but its still good that pikmin 3 sold out all other retail games in 3 days non the less(with the exception of 2 games)

missing out, the ideal date to get a wiiu is holiday 2013 imo. it'll have great games and better releases come 2014 MK8/SSB4/Zelda WiiU

I don't think I'll get it this holiday, since I already pre-ordered and paid off my PS4, so I think 2 consoles in 1 holiday is too many! But I still have 7 Nintendo systems to hold me over until I do.

I really don't see the point of this lists if we don't know how much those games have sold. But good I guess.
