Dudes still refusing to buy a Wii-U are pouring jelly on themselves at this point. There is aLOT of piff on the system. Not sure why folks are still playing Knack in 2014, thinking their next gen gaming.
Have you looked @ Console sales in Japan? They are flopping, even the PS4 with its "next gen" nonsense.
Bayonetta 2 got the Nintendo support because they were smart enough to get good games on the system. At this point, only the games matter.
