Well Nintendo is only one from all 3 that keeping they announcements much closer to release, so we really still don't know how Switch lineup for 2nd half of 2018. will look for sure. Saying that, if Nintendo is not going at all at E3, they would show their staff through Directs, so you can't really say they depending on E3, Sony and MS are more depending from E3 than Nintendo.
