"We will see all 24 houses and the leaders among them”

"They started with designing Klingon skulls. Page explained that DSC’s Klingons are bald because of these heightened senses on the top of their heads. The bald look was also a mandate from Fuller."

"In the different versions of Trek, the Klingons have never been completely consistent"
"Hopefully, fans will become more invested in the characters than worried about the redesign."
Basically, if you add all that together, you have:
1) We will see "all" 24 klingon houses - aka at least one member of every klingon family there is
2) All klingons on DIS will be bald
That leads to the conclusion -> klingons are now totally ret-conned to not have or ever had hair (because of the evolutionary idea behind the baldness). Which is pretty much indescribably stupid, in a universe where Worf
and pretty much any other klingon existed, with various different looks, hairstyles and ridges.
