Probably will. Less effort is needed in making a conference than making a Nintendo Direct and revealing the NX or its features plus its games is interesting enough to avoid spending time on a Nintendo Direct.
Personally, I prefer watching a Nintendo Direct because the transitions between topics are much nicer and its all about games and not a CEO coming on stage talking about numbers. We already get that in Nintendo's quarterly fiscal reports anyway.
They could start the conference with an animated/muppet sketch like the last two E3, though.
