There's always a Season 2 pass!
As for Chun-Li, her inclusion in the game is expected but if you play
Street Fighter 6 and Mai's story, her final boss is E. Honda, who would have been a vastly more intriguing choice for the second
SF character in this lineup.
When the inevitable season 2 comes, if they add more Capcom characters I fully expect Ryu. Guile would be another nice surprise. But it's unlikely we'll get any more crossover characters.
If I had to pick a Season 2 lineup, I'd go with:
- Nightmare Geese
- Yamazaki
- Duck King
- Kim Kaphwan
- Big Bear
If any of these are already announced, then okay.
I fully expect Kim Jae Hoon to be included at some point. Same with Kain R. Heinlein, since Rock's story is directly tied with him.
An older Hokutomaru would be interesting.
I'd even welcome back an ancient Jubei Yamada. This character gets no love from SNK.
