Since we are jumping from a thread to another thread to discuss about potential DLC so I presume that it's a time for us to trying to get us a home where we could discuss about future contents.
Currently Piranha Plant and Joker are out for us to purchase so we are still waiting to find out those four characters that would take their places in Fighter Pass. Our next hype stop would be at E3 for sure so it's quite exciting for us to find out who would be second character and potentially third character if we are lucky. Also there is a detail that specifically confirmed that we are getting more Mii Costumes as part of their DLC plans. Our previous question was; Are we going to get more contents than we are expecting? Beyond Mii Costumes and Fighters Pass? Yes, we did. We got Stage Builder and Share Function (where we would download stages, mii fighters, etc online.) Some fans are still hopeful that we would get more mode(s) in the future updates.
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
Dragon Quest's Hero is confirmed to be part of Smash Bros as Number 72. So we will see Luminary, Erdrick, Solo and Eight making their appearances in Smash Bros along with DQXI stage. More information is coming soon. Slated for Summer 2019
Also Banjo-Kazooie finally make their overdue appearance in Smash Bros as Number 73. The stage is obviously Spiral Mountain and their release date is Fall 2019. More information is coming soon as well.
RUMORS
There is no reliable information for next two upcoming characters so it's quite exciting that we are in dark for time beings.
Also I will update the title once hero is out so you have your chance to make your suggestion for better subtitle to emphasize the moment where we are yearning for Banjo-Kazooie.
