Not if it is published by nintendo.  That actually makes the game first party, developer considered 2nd party.  

Third party exclusives would be a game published by a third party.  

1. Nintendo will release a redesign for the Wii U.

More akin to the move from NDS to DSi, it will freature a more sleak design and try to visually distance itself from the original Wii. It will have more internal memory and better battery life for the gamepad. May come with a free pro controller.

Doubt it. Price cut, and a Gamepad-less model if they're bold/desperate.

2. Nintendo will officially reveal it's new QOL platform. It will release in the Fall/Winter of 2015.

50/50. They might want to talk about it to offset the damaging news which will likely emerge from their annual financial report.

3. Nintendo will announce a new Wii U Pokemon RPG.

Not developed by Gamefreak. It will be a spin off RPG similar in nature to Pokemon Colleseum and Pokemon XD: Gale of Darkness, but on a grander scale. The HD "Pokken Fighters" footage was actually alpha teaser footage of the game. It hosts the "new region" teased in Pokemon X and Y.

I think it's just "Pokken Fighters." It would make more sense with Nintendo's current direction.

4. Metroid 3DS and Majora's Mask will both be revealed for release this Fall/holiday season.

Good possibilities on both. 3DS needs something. But who's going to touch Metroid if not Retro or Sakamoto's SPD?

5. We won't see a new Metroid game for the Wii U at this year's E3.

Retro just finished Tropical Freeze and explicitely stated that they only work on one major title at a time. It's been hinted at that they'll be the one's working on the next Metroid, especially since it's recently gotten out that Sakajoke-o won't be touching it.

Indeed. Zelda will be the showpiece *new* core title. With perhaps more on X.

6. X will finally get a name and will be delayed until next year.

The latter is practically inevitable, at least for the West. Not sure about the former.

7. Shin Megami Tensei x Fire Emblem will have a trailer. Delayed until next year.

Again, inevitable on the latter. 50/50 on the former.

8. Bayonetta 2 will be revealed to release in the summer for Japan. Fall for the West.

This is basically confirmed already.

9. Hyrule Warriors will get an official name and release date.

Yes.

10. No one will talk about Yarn Yoshi this year. Again.

Quietly canceled is my bet.

11. Some new IP will be revealed. It will involve the NFC Gamepad thing, but try to distance itself from games like Skylanders and Disney Infinity.

Pokemon game. Perhaps ties into Pokken Fighters?

12. Pacman will be revealed as playable characters in Super Smash Bros. during the Digital Event or during the Smash Tournament.

They've got to save a TOP SECRET character this time. Though i do think Pac-man's in, i think they're going to try to hush-hush part of the lineup, especially since they're doing a simultaneous (or so) worldwide release this year.

13. A major Wii U exclusive Smash feature will be revealed at E3, as well as what will link the two versions.

Makes sense.

14. Wii U Zelda will be revealed and will release this Winter, either during the holidays or early 2015.

Early 2015 is my guess, unless it's a holiday title.

15. Star Fox Wii U will be revealed.

Nope. Who would make it?

16. Sonic Boom will release in October for Wii U and 3DS.

Makes sense.

17. Nintendo will reveal a new 3rd party exclusive.

Probably. A collaberation like Hyrule Warriors, though.

18. Nintendo will reveal their "Nintendo ID" cell phone app.

Who knows on this one. They're hard to predict on features.

 Connects to Miiverse, Club Nintendo, and eshop for both 3DS and Wii U. Marks the begining of Nintendo's unified playform.

I do hope you're joking.
