Ultra Street Fighter V (Final Season)

Before the release of Street Fighter 6, Capcom decided to do a true final season. In this season, all characters would come out at the same time with every content included. It also would include the final version of Street Fighter V, called "Ultra Street Fighter V", which includes fifteen characters with eight of them being guest characters (yet Biff and Skullomania would end becoming canon in the SF universe, so technically reducing the count to two) and for the first time in the series, some of those guests are from other companies.

Content

 * Fifteen new characters.
 * Seven were in a Street Fighter game before, the rest are newcomers.
 * Each characters have 6 costumes (including base).
 * New costumes for previous characters (between one and six costumes).
 * Some costumes comes from the guests franchises and represent characters from that games.
 * New moves for some previous characters.
 * Certain V-Skills are changed into regular special moves, those are replaced with new V-Skills.
 * Second Critical Art for every character in the roster, like in Ultra Street Fighter IV, you can select which CA you want to use in the character select screen.
 * Ten new stages.
 * Every guest character includes one stage (minus Rock Howard who shares stage with Terry).
 * Balance changes.

Trivia

 * Due to the amount of SNK characters included (the 3 protagonists of the "core" SNK fighting game series alongside the popular Rock Howard), many people started to ask if Capcom vs. SNK 3 would come next, Takayuki Nakayama expressed himself about that via twitter responding "We are in good terms with SNK, but we can't say that that game (referring to Capcom vs. SNK 3) will be our next project, but both sides are looking forward to have more collaborations."
 * The later was further proved with the release of the Team World Warriors (Ryu, Chun-Li and Guile) in The King of Fighters XV.
 * Other guest franchises (Tekken and Mortal Kombat) also received a collaboration with Capcom, adding Akuma in Mortal Kombat 12 and Sagat in Tekken 8 (alongside Akuma coming back).
