I just really can't see a January Direct being a repeat of the system's opening announcement.
The game we know by far the most about, Kirby, isn't coming out until at least April. And that's being highly optimistic of me, last time Nintendo announced a game for "Spring" it was late June by the time it came out. This is the game we know the most about. Kirby Star Allies. No, it's not coming out in January or February. They said Spring. It's not going to be out in winter. Kirby is a spring release.
We know of two other games that will for sure make the year, Fire Emblem and Yoshi. The former we've seen nothing of, the latter very little. These will both be treated as headliners for the next several months. People will get upset at this, shouting in fury at how Smash and Animal Crossing aren't announced.
Those will show up at E3. After six months of building negativity. Announced for 2019.
In the meanwhile, the Directs will mostly be the three games we know about, and new IPs. Lots of new IPs. Very casual new IPs. Less ARMS, more 1-2-Switch. Everyone will be frothing at how Nintendo wasted their development time on these games instead of -real- games.
They might sell very well despite it all, though. Or they could flop. The core gaming crowd will be rooting for them to flop because anything that isn't for them is against them or something. But they'll be upset whether they flop or not.
. . .Basically overhype is going to end in a crash. I can't see the next Direct ending too well when most people already have higher expectations than what we've had specifically told to us.
