Yorick Rework?

Last year I read a lot about what Riot was doing with the Yorick rework, and I got really excited because the necromancer fantasy is pretty diverse and amazing.

Then, nothing. All of a sudden they stopped talking about him and we haven't gotten anything else.

Was it canceled?

Was it delayed?

Or are they still working on him and just haven't said anything for a while.

I ask because his rework was started waaaaaay before people like Xerath, Skarner, etc.

Any sort of update at all would be nice :)
