@Riot Traditional Sejuani on sale?

I've been playing since the start of season 3 but I never got around to getting Sejuani until after she got reworked. When she got reworked her traditional skin was put into the vault and only to be seen by the likes of mystery gifts. The only reason I ever do mystery gifting is to get traditional Sejuani.

Will traditional Sejuani ever leave the vault like the other legacy skins? It's almost been 3 years.
