Wii U seems to be doing OK compared to the PS3 and the X360. We'll see how that goes throughout the rest of this month and the next few months...
39k vs. 144k (360) and 80k (PS3-no Europe) is extremely bad. No sugar-coating. It's just that, really, really bad. Look at the PS3/360 weekly sales going into Feb and March; WiiU sales are not going anywhere but down until there's a price cut and/or a system seller.
