[2020] About Tachanka's Rework

Lately I've realized that Tachanka is getting a rework, which is known now to be a pretty big step for Ubi. I now know that he's getting a Flame Grenade launcher which is supposed to be "spammy" meaning that it's going to have a lot of ammo. Also, his turret now is his primary and can be used as a soft breaching device. now when I'm think about it, what will his new "ability" be, since his turret has gone mobile? Also when is the release window of the rework?
