You did most of the work in the OP. How am I supposed to uphold my (self certified) reputation?

Man, why do people even bother with E3 anymore. It's not like you need to visit your local newsagent to buy copies of "GamesMaster" or "CVG" to hide your porno mags in anymore. The internet solved BOTH of those problems.

With some exceptions that doesn't sound that implausible.

I always try to keep my expectations at bay, but, we all know that as soon as people start rolling the hype train, we are all on board.

Don't go into E3 with any expectations be it positive, negative, high, or low. Clear your mind. Do not even think about what they are going to show. Then watch with a blank mind.

I think I'll let Nintendo do that for you

nintendo HQ will blow up before E3

Hah! Don't you know that there are really only two art styles in the AAA game industry?

1. Colorful, simplictic, and kiddy
2. Muted, gritty, and dark

Mixing the two would surely not boost the game's appeal in any way, shape, or form.

someone's gonna be disappointed soon.

3 Zelda's ?
Seeing Sonic Boom twice in the same conference? :P
other than that the Pokemon Z HD isn't really that likely as well.

Nintendo Digital Event is going to have a modified format than the Nintendo Directs we're used to seeing. Nintendo stated in the press release that it's a new kind of program that builds upon the ND approach. There's a chance they'll integrate live footage of people watching the video presentation outside the convention center. That's my guess.

If anybody were to bring Pokemon to the Wii U, I doubt it would be GameFreak. They seem to play it safe with platforms more than anything (hence why B2/W2 was on DS, not 3DS) and go with the big userbase instead of the untapped potential.
I think an NFC Pokemon game for Wii U is decently likely, but it wont be made by GF

I also doubt a new SM3DL game would be coming at all...more than likely EAD is doing something different with Mario. They usually don't like staying on the same thing for too long and I feel like there are not many more places to take the series.
New Mario is possible (though I doubt it) but I don't think it will be in the 3DL series.

Essentially, I think your predictions (or hopes?) are fairly realistic. Theres a few things (F-Zero, MM3D) that are one option in a longer list of options that I'm sure Nintendo has chosen a few titles from so we will see what they have chosen at E3...
