Capcom has announced Street Fighter V: Arcade Edition, a new version of its flagship fighting game that will be available for PlayStation 4 and PC from January 16, 2018. The updated version will include post-release content from Season 1 and Season 2 of the game, as well as a number of new gameplay changes.

In terms of characters, there will be a total of 28 fighters, comprised of the original roster plus the DLC characters, one of which is still yet to be revealed. More significantly, Street Fighter V: Arcade Edition will introduce a second V-Trigger for every character. This, according to Capcom, "will significantly change their playstyle."
