I play BoC, I can tell you that with all the hate the Bullgors got when they were released, no one cares now. New players like them, and they're completely unique in design amongst minotaur-like sculpts, they aren't going anywhere. There's no chance they'll put out a resculpt of them.
The real issue is that ALL the hero models available for BoC other than the great bray shaman (beastlord, doombull, shaggoth) are in resin, as are the centigors, jabberslythe, etc. I would prefer all of those get plastic kits before throwing us more god-aligned bs, since the lore of the actual battletome would suggest the majority of bray-and-warherds do NOT follow a god, and see getting power from a stronger being as something a weakling would do. It's fine that the god factions get some god-aligned beasts, but that's not why a BoC player plays BoC - otherwise we'd all just play those god books. With the rules they way they are for BoC, it's what most people have to do to be competitive, but in a balanced world that wouldn't be necessary.
Skaven definitely need the love first though, there is so much in that army that is not current and looks terrible comparatively. I hope that they get the plastic models they deserve sooner rather than later.
