@Riot KateyKhaos. Can we expect the next ultimate skin soon-ish or not for a while?

It's been about a year since DJ Sona came out. So the next Ultimate skin should be coming. I was wondering if you could give us a rough estimate of how long it would be. Say, could we expect it before summer, or not until fall/early next winter. I don't need anything exact, just want to know if I should keep my hopes up and check the PBE for it every two weeks. Or not have to expect it for a while.

Also, any hints on what role it is for?

Thanks for taking the time to read this.
