I add: good hold for Smash, Wii U doubled its own 2013 weekly sales but still behind YtD. I wonder if they will be able to repeat the good 2013 holiday season results. It will all depend on Smash, but with the huge success of the 3DS version, I'm doubtful...
If Nintendo's holiday bumps will be anywhere comparable to last year's then Wii U is already guaranteed to have a better YTD. Don't know if it will be comparable to it's first year but I'm guessing somewhere in the 500,000 - 600,000 range.
