I just hope they will be able to create some hype if NX is shown next year during e3. This is something the Wii U lacked off the whole time. However, I don't think a digitial event is the right way to introduce a new console. It would be a perfect moment for Nintendo to make a live press conference again. Don't get me wrong. I Like the directs but this is the e3, the most important event for video games. Nowadays even companys like Bethesda, Square and Ubisoft are holding press conferences while nintendo is doing a low budget format and yesterday they were given a lesson.
Besides, it is not to early to introduce a new console. The Wii U is doing poor and this won't change. They need to get the thirds back and this is not possible with the Wii U.
