As convincing as this leak looks, I'm still being cautious about it. The Rayman Leak (Smash 3DS/WiiU DLC era) and the Grinch Leak (pre-Ultimate launch era) should've taught us that that skilled/crafty individuals with the right tools can make fake leaks look very convincing and appear authentic. People should be even more cautious with leaks now. Not to sound like I'm trying to be negative here, but I don't want to commit to the leak and say "it's real, Geno and Doom Slayer are 100% coming". Hope for the best. Let's not jump to conclusions yet.

It's a bit early to dismiss the possibility of future post-Fighters Pass female fighters and give up. We don't know how many more DLC fighters are coming beyond FP#5. We just have a vague "more fighters are coming!", so it'll be 2 at minimum, but it'll be likely be more than that. Super Smash Bros. Ultimate is now the best-selling fighting game of all time, with
15.71 million copies sold as of the 30th September. Previously the title was held by Street Fighter II, which sold 15.5 million units (and that had multiple versions released since 1991). Super Smash Bros. Ultimate is also currently the second best selling game on the Nintendo Switch (#1 is Mario Kart 8 Deluxe, which has had 19.01 million copies sold to date). Nintendo will probably want to support this game for as long as possible, and Sakurai already said he wants to continue to add as many characters as he can. I'm sure there's going to be at least one female fighter or two that might be added in the future.
