Well there we go. But lol that it's on April fool's. Cue the jokes! But basically this will be release date announcements for things like Splatoon and Mewtwo DLC plus more apologizing about Zelda's delay and nothing substantial. It would be nice if they at least hinted at something to come later like at E3 or showed something on Star Fox which is still supposed to release this year.

I don't think they're ready to talk about NX so soon to the general public... I guess this is perhaps to set the tone for what titles we should expect to see for this year's E3 and what is going to end up being released prior to 2016.
There's likely going to be an apology segment for the delay of Zelda.
