When do we start getting hints about Urgot's rework?

Hey Riot, when will we start finding out about how Urgot is shaping up? Those leaked models have me, and I'm sure at least 2-3 other people, really curious. I know all the reworks thus far have been bug reveal surprises, but maybe you could have at least a little discussion similarly to what you've done with a few of the mini/class reworks?

Thanks!
