Here's a quote:
"Nintendo has announced that a new Nintendo Direct will be taking place tomorrow morning for North America. It will provide information on upcoming Wii U and 3DS games, and will start at 9:00am PST. We'll be covering the broadcast as it happens, so tune in to IGN early tomorrow for all the details."

The video will be released at 9:00 AM PT at this link: http://www.nintendo.com/nintendo-direct/archive/12-05-2012/

I personally can't wait. I'm hoping they reveal Yoshi Land for Wii-U and finally set a release date for Luigi's Mansion for 3DS

Yoshi's Land and more, hopefully. Doubt they will reveal any new games for 3DS.

eshop is down for maintenance at the moment, maybe an update?

Pikmin 3. Just, just give me A FREAKING RELEASE DATE FOR PIKMIN 3! AND FIRE EMBLEM: AWAKENING TOO WHILE YOUR AT IT! Okay, rant over.

Man they tease this every ND hopefully it'll actually be something BIG

My guess is its going to be about how great Wii U sales have been, when we can expect Wii U TVii, and maybe a small hint about the future of the virtual console.

Game and Wario! Where's my WARIO?!

I suspect there will be something about Luigi's Mansion Dark Moon, perhaps a trailer.

Maybe a few other miscellaneous 3DS and Wii U announcements if we're lucky.

Nintendo TVii will go live right after the broadcast?

There's also one for Europe!

I think we will hear some more information or release dates from (like everyone has said) Luigis Mansion, Animal Crossing and a few winch window Wii U games. I also predict a few more Eshop announcements and a couple of new retail game announcements for both systems...
Oh and something about Zelda U? Or maybe Mario Galaxy U?

miiverse for 3ds
release date for animal corssing new leaf

at least one of those two please!

Didn't they hint at a surprise launch window game at some point? Maybe we'll get that. I mean, I doubt it will be anything more than...I dunno a sequel to the Wiiware Excitebike game or something but I could see there being a new game announced, which is cool.

well we'll find tomorrow won't we? i think it will just be release dates for some of the games announced for early 2013.

New DLC for Nintendo Land will be announced. (Yoshi Land.)

Yoshi's Fruit Cart denies this :3

Probably Nintendo TVii is launching with Japan's WiiU so I would make sense

TVii app, Deluxe Digital Promo, and some new games will probably appear after it(release dates, feature updates at least). Maybe shared account between systems, too...

nothing we don't already know will be said in the NDirect. that's almost always what happens.

My guess is that they go over games we already know about (Pikmin 3, Luigi's Mansion, Animal Crossing) and then talk about some eShop exclusives on both platforms. Something about the Wii U VC is what I'm half expecting but anything that's a half expected feature that's currently missing. HD Classics, 3DS MiiVerse... they might even spend some time making us fall asleep by talking about a firmware update that improves performance/stability. Who knows.

The exception is when they're talking about system features, eShop content or a smaller game. They announced Mario Tennis on a random Nintendo Direct and pretty much every major eShop title including a fair chunk of VC games. They also spent a whole Nintendo Direct talking about the 3DS firmware update that added folders.... so it covers a pretty wide range.

The Yoshi's Island game? It could definitely fit within what they've done with Nintendo DIrect before. Something like Wii Sports? Maybe. Mario Kart? Less likely. Zelda/Mario/Metroid? Not happening
