Ubisoft holding back an unannounced, finished Wii U game until console sells more

Ubisoft has an under-wraps Wii U title ready to launch, but it is waiting to see if and when the console will sell more units.

Company boss Yves Guillemot revealed the news in a roundtable interview at E3 (thanks, Polygon), where he said that the unannounced title was finished and ready to be released.

"We have another couple of products that we are waiting to launch," he said. "Specifically we have one game that we wait for the machine to be more mass market to launch.

"[It] has been done for six months. It's on the shelf, waiting for more families to have the console."

Ubisoft was one of the strongest third-party supporters of Nintendo's console at its launch in 2012 - but new Wii U announcements from the publisher have tailed off, and the Wii U version of Watch Dogs was delayed to release the other platforms sooner.

"We did adapt the number of products to the level of quantities that the machine did," Guillemot explained. "So we will have Just Dance again which is well suited for the machine. We'll have Watch Dogs. "

Ubisoft was not willing to divulge exactly how much more units Wii U needed to sell before it would release the game.

"We don't have a number," Guillemot added. "We need the sales to increase so it becomes more and more mass market then we will have the volume that will justify massive marketing and TV marketing.

Should Wii U never achieve the sales required, the game may be released instead on another platform, he concluded, although the company will "wait for Smash Bros. to come" before making any firm decisions.
