EA and Sony have declared that they won't be taking part in E3 2019, but that has done little to slow down their competitors, as Nintendo is gearing up for its conference by creating a website in order to promote its next E3 showing.
Nintendo's E3 2019 website has laid out the plans for the upcoming event, which will include the Super Smash Bros. Ultimate World Championship 2019 3v3 and Splatoon 2 World Championship 2019 tournaments that will be held on June 8 and will be streamed online. The actual Nintendo presence at the event will be June 11-13, which is the timeframe during which it will most likely make any announcements or show any reveal trailers.
The website doesn't give any details about any of the games that will be shown at Nintendo's upcoming E3 conference, but there are a few educated guesses that can be made. There still hasn't been any new information revealed about Animal Crossing for the Switch, which is due to be released in 2019, and there have been rumors circulating about new models for the Nintendo Switch that are meant to be revealed at E3.
There are other Nintendo Switch games that we know little about that could also make an appearance at E3, with Bayonetta 3 being chief among them, as it was briefly mentioned during the last Nintendo Direct. Joker will be available in Super Smash Bros. Ultimate sometime in April, which means that the next DLC character from the Fighters Pass is still awaiting an announcement. There are also some titles that have been rumored to be in development for a while now, such as the mythical Star Fox: Grand Prix and the supposed revival of Scalebound, which was originally a Microsoft exclusive game that was canceled but was rumored to have been picked up by Nintendo.
Nintendo made a huge mistake with its E3 2018 conference by focusing too much on a single game, as Super Smash Bros. Ultimate took up the bulk of the time. It seems that the long-awaited announcement of Ridley wasn't enough, as Nintendo's stock value actually went down due to a lack of other announcements. There wasn't much at E3 2018 for the Nintendo fans who don't enjoy the Super Smash Bros. series and Nintendo isn't likely to make the same mistake twice.
One thing that we know for sure will be missing from E3 2019 is Reggie Fils-Aimé, as he will be retiring from his position as President of Nintendo of America on April 15, which means that if he's attending E3, then it will be as a fan.
The Nintendo Switch has had a strong start in its first two years, but the system may soon be facing opposition from the likes of Google Stadia, PlayStation 5, and the successor to the Xbox One, so Nintendo will need a killer lineup of games going forward if it wants the Switch to stay relevant. The 2019 lineup for the Nintendo Switch could still use some fleshing out and we know almost nothing about what is to come in 2020, so a lot will be riding on their upcoming E3 event.
Nintendo's E3 conference is due to take place over June 11-13, 2019.
