With the big reveal in 11 days, there will be a lot shown, but I am not sure they can cover everything.

So what I am wondering is if we might see some directs between then and the release of the game to flesh out bits that they can't cover during the reveal. 

For example Directs on Breath of the Wild and another covering another game, perhaps the Rabbits rumored game. 

So what do you guys think: will we get a Direct(s) later in Jan, Feb, and March for Switch games?

I hope so.

Doubt it, the will probably be an ND shortly after it releases.

We will probably get a decent Direct a week or two before the launch date. To give to the Switch all the attention they possibly can during launch.

I doubt we'll see one until after the Switch launches.

I expect one in Feb at least. One of like 60 min longs or perhaps two smaller ones of 30 min. This would/should show all the upcoming software year since the 1ste NS year must be a success.

Actually, maybe this.

Probably at least one before it launches

It may or may not be a direct specifically, but there's definitely gonna be some form of continuous news, no way they're just gonna go silent for three months and launch the Switch quietly.

IMO definitely we will have some NDs about specific games.
