Mario Kart 8 has helped to boost sales of Wii U, but Ubisoft CEO Yves Guillemot still thinks Nintendo's pricing of the hardware will be crucial if it's to increase its user base and justify further investments.
"With Mario Kart, Wii U made one step and we expect with Smash Bros. it will also do more. If Nintendo put the right price on the machine then they will probably have a chance to do further," he said in a recent interview with CVG, somewhat subtly suggesting the need for a price drop.
Ubisoft continues to be one of the Wii U's key third-party supporters, but even it is holding back on further investments - including a new unannounced title - until Nintendo can justify the support with a sufficient install base.
"We are coming with Watch Dogs and Just Dance this year. We also have another game on the shelves that we expect to come at some point when there will be more machines," revealed Guillemot.
"That game is waiting for more machines to be available," he added, in reference to the 'availability' of Wii U owners and, thus, potential customers.
"We are also waiting for them to achieve more sales so that we can invest more. Because the problem we have with next-gen now here, is that we are seeing less games that are on next-gen and last-gen consoles.
"Nintendo has to perform this year, otherwise they will have less games. Justifying investing in the machine needs a larger install base," said Guillemot.
In a statement at E3 earlier this month, Nintendo of America boss Reggie Fils-Aime was keen to stress that the Wii U is currently running second in the next-gen console race, ahead of Xbox One in terms of "life-to-date numbers" globally.
"I think it's going to be a three-horse race for the balance of this cycle," predicted Fils-Aime.
