delay was over concern of low sales on and of Nintendo's Wii U.
"What happened was that we saw the Wii U was not going to sell enough of those games. The game is going to be fantastic, and we didn't want those creators to wind up in a position where even after making a fantastic game, they didn't sell well enough," Guillemot told VentureBeat. "We decided that we had to come out on enough machines that players can try it out on any one that they have, and give more time to both improve the game on the Wii U and create versions for the other consoles."
Low sales of Nintendo's latest console has certainly had an impact on third-party support. EA acknowledged it needs to see stronger sales to get back involved, and although Activision has Skylanders for the platform, we're still waiting for confirmation that Call of Duty: Ghosts will make it on the platform. Although, it should be noted that historically Activision's announcements of CoD on Nintendo platforms arrive later.
Nintendo is aware of its current predicament and hopes its first-party games between now and 2014 make the Wii U more attractive again.
