E3 2010 - Nintendo press conference live!

Have you got a shelter built? Have you dug a hole? Because today is serious, son.

Nintendo's up first today after Microsoft's E3 showing last night, with Sony to follow soon afterwards. But undoubtedly, this is the most important conference in this year's show, as well as one of the most important within the past five years.

How so? Two very specific reasons.

One - 3DS: We finally get to see what the handheld looks like later today after months of speculation, and is the first big hardware reveal out of the big three since E3 2005, as well as Nintendo's first massive hardware reveal since 2004 with the original DS.

Nintendo's promise of 3D gaming without glasses does sound like a pipe dream, but there is potential for it nonetheless. EA CEO John Riccitello has already said he thinks the tech is "cool". You can not get a bigger thumbs up than that.

We may even hear confirmation of the previously rumoured release date of October, as well as the possible first sightings of Animal Crossing 3DS and Level 5's Time Travelers, which seems like it will support the console, according to past hints.

Two - Zelda: Twilight Princess was all well and good for appearing on Wii, but it was just a port of the GameCube version. Today will bring the first showing of a brand new, and true, Zelda Wii title.

What do we know so far of it? Other than the piece of art shown by Shigeru Miyamoto last year and that it's a WiiMotionPlus exclusive, absolutely nothing. Unofficially? There might be this.

Hopefully we'll get confirmation of a release this year as well. Be sure to produce something like this for a crowd reaction anyways, Nintendo.

There's also a whole lot more that we don't know about so far, but those are the big two. Whatever you do, keeps those eyes glued to the screen just for those two things.

Pat and Nathan will be there for us with a liveblog, naturally. Needless to say, you won't miss a beat with us. It all begins at 9am PST/5pm BST/6pm CET.
