Nintendo CEO Satoru Iwata has confirmed, through his Nintendo Direct broadcast, that Mario Tennis Open on 3DS will be released in Japan on 24th May. It's the latest first-party offering to be released as part of Nintendo's revival of the handheld, and it's the fourth time — including Virtual Boy — that Mario has taken to the court in portable form.

It seems perfectly likely that a worldwide release won't be too long in coming after this announcement. While we're still waiting for more details on the title's content and features, is this one that you're interested in picking up?
