Ubisoft's CEO has said the company is holding back a finished Wii U game until the console's user base grows sufficiently to warrant marketing investment in the title.
Yves Guillemot told Polygon that Ubisoft is being careful with new Wii U projects until the console's sales numbers pick up.
"We did adapt the number of products to the level of quantities that the machine did," he said, "so we will have Just Dance again which is well suited for the machine.
"We'll have Watch Dogs. We have another couple of products that we are waiting to launch, specifically we have one game that we wait for the machine to be more mass market to launch."
When asked how many more Wii U consoles Nintendo would have to sell before Ubisoft would release the game, Guillemot refused to specify.
"We don't have a number," he replied. "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.
"We have a game that has been done for six months. It's on the shelf, waiting for more families to have the console."
In July 2013, Guillemot bemoaned the poor sales of Wii U launch title ZombiU, saying there were no plans for a sequel because the game wasn't even close to making a return on the publisher's investment.
Guillemot is also said to have cited ZombiU's poor performance as the key factor behind switching Rayman Legends from a Wii U exclusive to a multiplatform game.
