So some weeks this year the Wii U was selling really bad, like 20-30k, so what's gonna be the worst selling week for 2014?  

Personally I don't think Wii U will reach anywhere near that low in 2014, it looks like its starting to catch on in Japan so that should add a nice boost and Nintendo's really marketing it, hopefully that doesn't completely disappear after the holiday season, and its got a healthy supply of games coming out, we won't have anything like the drought in 2013.  I'm guessing the lowest its gonna fall is 50-60k.  I think its probably gonna get those numbers in the start of the year, before DK comes out, but after that I don't expect it to fall that low again.  

40 - 50k?

I seriously think 2014 will easily sell 1.5-2 times as much for Wii U hardware as it did in 2013.
