Here's a bunch of stuff you already know about.

The XY portion of that Pokemon Direct was 4 minutes. Omega Ruby and Alpha Sapphire got a half minute.

They could potentially mention Pokkén and the VC releases before dropping XZ/YZ at the end. (Since it's the same video for all regions, they wouldn't do Detective Pikachu here.)

Dropping Detective Pikachu in the West was my initial thought with this. But seeing as how this is being broadcast simultaneously all around the world, there will be more than that (but probably something about it for the West). Maybe a blow out on Pokémon Go?

Pokemon Snap 2 for Wii U, it's happening!
Also Wii U Lan-cable for Pokken is announced, new Pokemon in Pokken, Amiibo support in Pokken, Pokemon Go, Pokemon Amiibo cards and lastly Pokemon Niji is announced.
And a new feature film!

The new announcement is actually going to be a Nintendo-developed mobile game. Set your expectations accordingly.

I heard Pokémon Go was being blown out at GDC so I expect this to be a reminder that Red/Blue/Green/Yellow are out and that Pokken is coming out, along with the announcement of codename Niji. If we're lucky they might add in some detective Pikachu for the west.

I can't imagine how having Detective Pikachu localized would be considered lucky.

My consistent "next Direct" prediction involved coming around Pokémon Day, so I'm glad to see that came true.

Do get ready for a lot of recycled info early on.

As much recycled content as they can shove into a five minute direct before putting a tease for Pokemon Z right in the last 10 seconds.

Give me Detective Pikachu, Nintendo

Five Minutes?!?!? What the heck? What can they do with five minutes that's in any way impactful? "Hey watch a game trailer. Buy this game. Peace out" ?

Voiceover: "As you know, this year is the 20th anniversary of Pokemon. We're celebrating with Pokemon Red, Blue and Yellow releasing on the eShop, with new wireless trading.

We also have Pokken Tournament releasing on March 18, featuring some of the greatest Pokemon of all time battling in majestic Wii U arenas. Preloading is available now on the Nintendo eShop, and those who preload will receive a special card for Shadow Mewtwo.

But finally, we have a new Pokemon RPG for the 3DS, releasing later this year."

"Pokemon XYZ will feature a brand new adventure in the Kalos region, in which you must gather the pieces of the Zygarde Core to form Perfect Zygarde and save the world from the evil Team Flare. See new areas, and take on new challenges the likes of which you've never seen before. Pokemon XYZ will release worldwide on August 13.

Thank you for watching."

Also, why aren't the links to the Nintendo Directs ever in the articles?

Worst direct ever.

It said in the article that it would only be 5 minutes. I thought it had to be an error. nope.

"Nintendo no longer does Directs. All they do is press dumps now."

"Why was this a direct?"

I'm going to log off for a while...
