The Wii U won’t make it to the 2014 holiday season, says former Sony developer Kenny Linder.

The Little Deviants developer added that Nintendo made such a mess of marketing Super Mario 3D World, that “no one gives a sh*t” about the game.

Linder made the comments in a lengthy post on NeoGAF that he has since edited.

“Releasing [Super Mario 3D World] 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,” said Linder.

“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.”

Linder’s remarks follow former Naughty Dog and THQ boss Jason Rubin who overnight described Nintendo as “irrelevant” in the console space.
