My prediction based on what we've seen is that their combat stats will remain largely the same, they'll be 4 wounds, 4+ save with the auto regen. Gaining +1 wound in Glogg's Megamob, meaning they're still great in other subfactions but if you want the most out of them you go Glogg's. Their move and bravery is probably still the same. 180 points.
I suspect the Dankhold Troggboss still won't be a Monster, as this avoids a degrading statline (usually but not always like the Tauralons are monsters but don't degrade) however there'll be a Warlord Trait like the StoD Demon Prince for +2 wounds and gain the Monster Keyword. This could mean a 15 wound Troggboss at maximum due to Gloggs. I expect their attacks to be something like D3+2 damage. The Pet Gribbly Squished token makes me think that Troggbosses may come with Glowy Howsit in-built, though in this case the Gribbly is protecting him. The token is to signify when you've rolled a 1 and it breaks. Crushing Grip is probably the same and he probably has his reroll 1s to hit as an always on aura.
