Ubisoft has begun shifting its focus on Nintendo's Wii U console, with CEO Yves Guillemot dealing the final blow in a recent Game Informer interview. While the company will continue to release games like their popular Just Dance franchise, the fledgling console won't be seeing any further "mature" games past Watch Dogs.

The writing has been on the wall for awhile now when it comes to Nintendo's lack of third-party titles outside of the traditional regurgitating franchises seen across all platforms, and Guillemot hasn't played it down. During the interview, the CEO reveals that part of the reason for the shift is due to the poor reception for Assassin's Creed games on Wii U. Both Assassin's Creed 3 and Assassin's Creed 4: Black Flag received Wii U versions, but neither game appears to have done as well as the Just Dance games.

"What we see is that Nintendo customers don't buy Assassin's Creed. Last year, we sold in very small numbers," Guillemot told Game Informer. Nintendo consoles declined from 20 percent to 14 percent of the company's portfolio over the past fiscal year. Ubisoft's CEO also suggested that due to the high uptake of new-gen consoles the company could be phasing out PlayStation 3 and Xbox 360 support as early as next year.

"What we see is that this year is still fine for the PS3 and 360, but next year because they are selling very quickly, we'll move to the new hardware," Guillemot said. "After 2015, it will be hard for us to create games for those systems."
