Big Nintendo announcement on the way?

Looks like Nintendo has some exciting news to share, with a big announcement apparently just around the corner.

The US Official Nintendo Magazine (as read by IGN) has promised there is "something very special lined up" for the next issue, due to hit the shops on 12th March.

Meanwhile, Nintendo has invited US journalists to attend a Media Summit in San Francisco on 24th February. Presentations, demos and hands-on playtests will be on offer.

So what could it be? New Zelda? New Mario? New Women's Murder Club? Nintendo's declining to comment, so it looks like we'll have to wait and see.
