During E3:

1. the Switch is going to get atleast one significant game that is going to piss off the incorrectly named "core" gaming community.
   * First time in last few E3s this didn't happen.
2. the Switch is going to have the longest lines and attendance of any other product.
   * Saw videos of people running to Nintendo's booth area. Too lazy to hunt for data-driven answer, but based on Odyssey appeal and the many, many reports that Nintendo won E3, I'm just going to say this was a win.
3. the Switch is going to get support for at least one major AAA game launching in 2018.
   * Sadly, nothing was shown but Beyond Good & Evil 2. However that game is not 2018.
4. EA is going to continue to be a dick-hole with "unprecedented" low-quality support in an attempt to repeat WiiU blacklist for all EA yearly franchises.
   * True - no other yearly games mentioned yet. (probably coming in 2018)
5. people are going to really not like Switch's phone/app/chat system. Nintendo has to Nintendo something otherwise its not Nintendo.
   * True - few interviews pushing in on this concept. Clearly not liked. But not fully explained yet either.
6. it'll be clear 3DS is being laid to rest.
   * Arguable. 3DS this year is light though big Metroid game announced.
7. Metroid or Pikmin will be teased for 2018
   * WIN!!! Metroid Prime 4. :) Though not in 2018 and surprising not big mention of Pikmin either.
8. Virtual Console will be a no show and instead Nintendo will highlight the online service and its Classics  library offering.
   * True
9. We will finally get to see what Retro has been doing... a 2018 game.
   * Nope. Retro is not doing MP4 and nothing that was shown was directly mentioned as a Retro game. 
10. First Apps will be highlighted for Switch. (I actually don't want this, but I think it is inevitable)
    * Actually nope. Maybe they'll stick with what I want and no apps ever. Just pure gaming console. 

That is Xbox right there I am pretty sure that's what you mean there, yes.

The thing is Nintendo has a great amount of content that can easily push it through 2017 so I think there will be a lot of teasers for 2018.

In my response:

1.) Yes
2.) Yes, thanks to Mario Odyssey
3.) Yes
4.) Yes
5.) Yes
6.) Possibly, I think there's going to be 1 more full year of 3DS Support before Nintendo jumps ship. There's still a lot of selling potential there. Especially for the rumored Pokemon Stars, Dragon Quest XI, and the rumored Mario and Luigi Superstar Saga DX.
7.) Yup
8.) I hope not, Virtual console needs to be detailed asap I think. Or at least let us know it's being worked on. Nintendo has stated the NesFlix type program won't replace VC but they never say VC is necessarily coming. I'm sure it is but we need more details and more games to fill in any gaps where I don't want to buy a game like Splatoon 2 or something.
9.) Of course
10) I assume that the 2017 mobile app will be shown and hopefully a web browser...but other than that I wouldn't expect much.

Add to the list MH5 exclusive for NS and that's all.

I like he's predictions....

Ha, if that gets announced, it will itself cover like half of his predictions.

Probably the bolded part of your sentence.

Core core core.....

Are we talking the Tomb Raider X-Box thing, or worse?

1. You must be new here if you think something going multiplat doesn't cause huge outrage. 

Metroid or nothing :D
