Nintendo of America to hold own Nintendo Direct tomorrow

Seems like it’s not just a Nintendo of Europe thing after all, Nintendo of America have also confirmed they plan to hold a Nintendo Direct presentation tomorrow.  Here’s the official word about it from their Twitter account:

So if you’re after the latest 3DS and Wii U news and don’t want to watch the European Nintendo Direct, there’ll be one at 9AM PT tomorrow with much the same information. Does this mean there’s something big that Nintendo plans to formally announce tomorrow?
