We haven't seen much of Super Mario on 3DS save for a few early screenshots, causing some to speculate the game won't see release until 2012 at the earliest. However, Mario creator Shigeru Miyamoto wants to assure fans that he's doing everything to bring a new Mario game out this year.
Speaking to GameBlog.fr, Miyamoto said:
Je vous promets de tout faire pour vous livrer le nouveau Mario cette année!
Which a quick run through Google Translate reveals as:
I promise to do everything to deliver your new Mario this year!
Of course this doesn't necessarily refer to Super Mario on 3DS and could be a hint at a further Mario game for release this year, but we'll find out more about Nintendo's plans at E3 in early June, or potentially next week's much-anticipated investor's meeting.
