Next legendary skin any coming out soon? (even tho dj just did)

One per year...approximately. Sona's only the third and we are entering season 5, so we're behind by one, if that were the case.

I haven't seen anything on a new legendary skin yet. And I follow the PBE stuff and rumors and stuff on the boards and Reddit. So if there was any info, I would probably have heard it. I know it's an ultimate but DJ Sona just came out so Riot probably won't release a legendary too soon after the ultimate. Going by past releases, I would say they will release the next legendary skin in April at the soonest.
