This skin got teased on the "Demacia Vice Squad Promo 2" as seen one the leagueoflegends.fandom media tab

This skin could be released with a running animation from base where she would use the roller blades as seen on the promo 2 picture

With these high contrast and vibrant colors Vi would once again have a funny and less serious skin

This argument can be supported because all her last skins after Neon Strike Vi where more focused on being cool and have more of a serious feel to them
