I will update this post when we get more info. Feel free to comment anything I may have missed!
They released a short teaser trailer for Street Fighter 6. It doesn’t really tell us much besides that it includes the worst character and Ryu.
Edit 2002-06-02: A couple new trailers show off new characters, locations, modes, mechanics, and some gameplay.
Edit 2022-06-03: LEAKS!
“Chinese assassin lady with a hairstyle like Sawada from Kengan that wears a black dress and uses poison like FANG.”
“Yun and Yang’s cousin (wears yellow, uses Drunken Fist style)”
“Dandy Russian with Psycho Power in an peach/orange colored suit”
“African-American ninja girl with with an orange hoodie, black pants, wears earbuds and has blue highlights in her hair while using rollerskates”
“Mexican girl in a green tunic with an Aztec weapon (noted to may have some kind of relation to T. Hawk)”
“Italian wrestler woman with red hair and an MMA legionnaire look that wears black & gold”
It should be noted that Kimberly is confirmed from this screen of the official trailer, so it can be assumed the leaks are pretty trustworthy info :-)
