Nintendo is hosting a new Direct presentation tomorrow www.neowin.net

The last time Nintendo held a proper Nintendo Direct presentation was at this year's E3, which saw many big reveals, such as a sequel to The Legend of Zelda: Breath of the Wild.
With some time between then and now, the Japanese company is ready to deliver another presentation, and it's happening tomorrow.
The announcement, made through Twitter, says the presentation will focus on titles coming in 2019, including Pokémon Sword and Shield and Luigi's Mansion 3.
Some users also expect SNES games to make their way to the Nintendo Switch Online service, as Nintendo recently filed trademarks for wireless controllers styled after the original SNES.
Nintendo did something similar with the launch of NES games, which happened almost a year ago now, so this is a plausible theory.
