Nintendo's Digital Event only 30 minutes long?

If it was only 30 minutes, why would e3 Treehouse start at 11.35, over 2 hours after the presentation has ended?

I think this 30 minutes thing is wrong, I think it'll be at least 50 minutes, and there'll be some sort of official post event that takes the whole thing close to an hour and a half.
