There are rumors circling about an upcoming Nintendo Direct that will likely be the last one before E3 2019. This Direct might be coming sooner than anyone thought, as some believe that it will be happening this week.
Sources close to Gaming Intel have claimed that the next Nintendo Direct will be held on Thursday, April 11, 2019, though there isn't any word on what will be shown during the Direct nor any announcements relating to hardware or software that will be made.
There have been rumors circulating about Metroid Prime Trilogy and Persona 5 coming to the Switch, with the latter possibly pre-empting another announcement that is due to be made by Atlus in a few weeks. Masahiro Sakurai stated at the Famitsu Awards that Joker will be arriving in Super Smash Bros. Ultimate soon, so we might see him after the Direct, along with the promised Spring Update that will hopefully banish the Inkling's Splat Roller to the darkest pits of Hades where it belongs.
The rumored Nintendo Direct would also be the last one before Reggie Fils-Aime retires, which will give him one more opportunity to crush the hopes of Mother 3 fans before he goes off to live on a beach somewhere.
There have also been rumors that Animal Crossing is due to be the featured game at E3 2019, so it's possible that the big closing video of the upcoming Direct could be a tease for an Animal Crossing-themed Direct at E3.
The Nintendo Labo VR Kit is due to be released on April 12 and, while Labo sets generally aren't featured as part of the proper Directs, there might be an exception made if games other than Super Mario Odyssey or The Legend of Zelda: Breath of the Wild are receiving VR modes.
There might also be an announcement related to adding Labo Blaster support for some old light gun games (like Duck Hunt or Hogan's Alley), which could be added to Nintendo Switch Online in the future, along with Virtual Boy games for the VR Goggles.
The 2019 lineup for the Nintendo Switch has mostly consisted of Yoshi's Crafted World and a lot of the upcoming games are still lacking a lot of vital information. The rumored Nintendo Direct might finally be able to clear up a lot of questions about the release schedule for the rest of the year.
