So now that we know Nintendo Directs will continue, will they show Zelda in the next one or?

Don't bet on it. They went through the year last year after E3 not showing anything until the Game Awards, and then after that, the next update they did regarding the game was the announcement of it getting delayed.
They want to save the title for a big announcement on a big stage, like this year's Game Awards or E3 2016, as their main title to show off on the floor.
