Updates on Ebony Maw and Cull Obsidian Balance Changes?

MCOC Team said:

Cull Obsidian:

After looking at our data across all the game modes we have determined that Cull Obsidian is out damaging every other high-damage Champion in the game. While he does have his limiting factors, once he's fully ramped up he is able to end fights before even high-level Opponents can do any meaningful damage to him.

The goal of Cull’s rebalance is to make tuning changes that keeps Cull Obsidian as one of the top damage dealers in-game.

Ebony Maw:

You said it and we saw it in the data. Although Ebony Maw is a decent Defender, he is underperforming as an Attacker (the designer said something about his Degeneration DPS being just sad and wrong).

We are looking to boost both his defensive and offensive potential, but with an emphasis on offense.

Cull Obsidian and Ebony Maw’s balance changes should be live in approximately 3 months.

It has now been almost 2 months since this post was made. Are the changes going to be live (not on beta servers, live in production) by January? Are we getting beta servers? I for one can't wait for ebony maw buffs, one of my favourite characters but his damage is just tragically low to the level of being unusable.
