I hope that happens and they bring at least 2 big surprises.
I can see pikmin 4 in the beginning, more details of the announced games and dates, some that we know that eventually would come but never showed like shin megami tensei and DQ11, some ports/remakes/HD collections, finish with joker footage on smash and announce persona 5

Nice ND "leak" at IGN Forum...

Too good to be true, right?!

My 'somewhat high' is tongue-in-cheek. To be honest, given what we already know is coming, plus the potential for more third party announcements, I won't be that disappointed if Prime 4 and Bayonetta 3 only ship next year. If they're coming this year, I don't expect we'll get any other new 2019 games outside of previously announced stuff, a Labo pack and a port or two. I'd take Prime Trilogy HD this year and Prime 4 next year. Bayonetta 3 is a possibility - Platinum have said they have a busy 2019 lined up.

I also didn't say Retro would launch something this year, but a reveal coming in a January Direct is extremely unlikely. I'd be happy if Nintendo gave firm dates for Yoshi and Fire Emblem, gave a release window for Luigi and Daemon X Machina, and announced some more third party content for this year (especially the rumoured Persona 5 R).

I'm actually thinking we'll see Pokemon in the Spring or Summer (given the history of the franchise) and Animal Crossing for the holiday season (again, given the history of the franchise).

I'd be a little surprised if Pokemon wasn't on the first Direct of the year.

As for the so-called "leaks" - they're mostly saying that Nintendo is going to be revealing games they've already shown before. The same sort of predictions happened for last year's January Direct, and they were ALL WRONG!!!
My guess is that it's not going to be a Direct focusing on a bunch of crap we've already seen, but mostly on new reveals, and probably not all the big games people are hoping for, but rather the titles they want to highlight for the next 4 months or so, perhaps one big one for the Summer.
But seriously, I don't fucking know what Nintendo is doing, they've been changing things up a lot over the past two and a half years.

I mean, I'd LOVE to see more Final Fantasy footage (FF7 on a Nintendo console is monumental! Particularly for those of us old-time fans who went on adventures to get Squaresoft games back when they were practically a branch of Nintendo), but it's been done, and I don't know if they'll show it again except if it is a brief "Here are some release dates" thing.

Pokemon is already confirmed to release in the second half of 2019. Also, it wouldn't make sense for the most ambitious Pokemon games yet to release sooner after the previous generation than any other Pokemon generation. Three years is the absolute shortest gap that there's been, and Sun/Moon released in November 2016.

Summer is in the second half.

Sun/Moon releasing in November was an abnormality for the franchise.

???

November is the most frequent month for a Pokemon generation to launch, and, even taking the absolute most generous definition of summer, only one Pokemon gen launched then: Black/White on September 18th.

February (1): Red/Green - 27th
September (2): Diamond/Pearl - 28th, Black/White - 18th
October (1): X/Y - 12th
November (3): Gold/Silver - 21st, Ruby/Sapphire - 21st, Sun/Moon - 18th

Let's Go: November 2018
Ultra S/M: November 2017
Sun & Moon: November 2016
ORAS: November 2014
X & Y: October 2013

The last games to be released in summer in Japan were B&W2, but they only got released in October in the west.

Pokemon isn't gonna be reveal until May to tie in the release of Detective Pikachu I bet.

Seemed someone took to Twitter to do a fake announcement that has fooled a number of people and outlets.
