Currently the Fighters Pass 1 are completely done and out for us to purchase but the ride isn't even over. Sakurai announced that we are going to get 2nd Fighter Pass and we're waiting for third reveal. Currently there are four more fighters that are still remains as unknown to us . Our next hype stop would be more likely to be at Smash Presentation so it's quite exciting for us to find out who would be eighth character if we are lucky. Also we are still getting more dlc supports outside of playable characters which are Spirit Events, Tourney and Mii Costumes. And maybe random update like Small Battlefield.
It's a season pass for Super Smash Bros. Ultimate which will contains all five planned DLC packs. Those DLC packs each come with a fighter, a new stage and additional music tracks. You could save 5 dollars overall by purchasing the Fighter Pass, which costs $24.99 USD. However, if you aren't comfortable paying upfront, especially without knowing the details of the DLC contents, then each pack individually can be bought for $5.99. As an additional bonus, if you get the Fighter Pass then you will obtain a free Xenoblade 2's Rex Mii Costume.
CONFIRMED
Steve and Alex from Minecraft got confirmed. Also We're still awaiting for the identify of eighth and future characters so there is no reliable leak at the point. Also it's confirmed that we are getting more 4 more characters so we don't know how long this hype train would lasts this time but it's definitely more than a year for now. It's mostly speculated that we will find out about 8th character in 2021 but hopefully we're wrong about this (SmashERA laughs).
RUMORS
There is no reliable information for upcoming characters so it's quite exciting that we are in dark for time beings.
