According to Kenny Linder, the former Little Deviants developer, Nintendo's Wii U won't see another Christmas, and "nobody gives a s***" about Mario.
The comments came in post on Neogaf, which were later removed except for the following statement: "Yep. Releasing it the same day as PS4 in UK/EU wasn't wise. The frustrating thing was this game was probably ready to go in October."
However, the full post was copied by Nintendo Life before it was amended: "Releasing [SM3DW] the same day as PS4 in UK/EU wasn't wise. The frustrating thing was this game was probably ready to go in October. I think retail and the market will push Nintendo in a direction whether they like it or not. They MUST be in danger of losing shelf space at this point. Retail will have four major consoles (PS3/4, 360/One) plus 3DS/2DS to push which will all move units, and it looks like Mario can't help even poor Wii U out. If it goes from shelves, it will be finished. I am still confident in my crazy mind that Wii U will not see another Christmas after this one. But that's just me. The future games will just get moved/axed."
"Releasing Mario on Friday was a really stupid thing to do, it could of come out weeks before that. I wonder if the same gamers who buy Nintendo home systems (150k of them in UK) are the same gamers that buy PS4/Xbox? That might explain lack of sales this week. Otherwise, nobody gives a s***. Also, I haven't seen a single Mario 3D World advert on UK TV, whereas the other two (PS4 more so, especially last night, holy s***) are on all the time. They have failed to see what the market wants."
As pointed out by Nintendo Life, there has been adverts on television, so Linden isn't entirely correct in his final point, but he does raise some interesting thoughts in other areas of his post. Nintendo's console celebrated its first birthday last week, you can read about its tricky first twelve months in The Wii U - One Year On.
