The Wii U may be struggling so far, but you shouldn't bet against the system just yet.

That's according to Sony Worldwide Studios president Shuhei Yoshida, who said recently on talk show Kurokawa Juku (translated by Kotaku) that a slow start doesn't always mean poor performance in the long run.

"The latest Mario game is really good, too. I think the Wii U is just getting started," Yoshida said, adding that he owns two consoles himself.

"People can get together and enjoy [the Wii U]; it's got plenty of wonderful games." Yoshida added. "Nintendo helps raise and teaches the fun of games to people just starting out. I think that's a very important thing in this industry."

The Wii U has sold 3.91 million units across the world so far, below Nintendo's own expectations. Still, the company is sticking by its previous estimate of selling 9 million units by the end of its fiscal year in March 2014.

Earlier this week, Nintendo of America executive Reggie Fils-Aime said Nintendo is spending "substantially more" to market the Wii U this holiday compared to last year.
