in regards to the rumour of updated battletomes coming for older 1st edition books, why are people expecting Kharadron Overlords to be one of them?
im aware people think theyre bad right now, but as that is a newer book with allegience abillities etc i wouldnt expect to see them getting anything at the moment.
the books i would expect to be updated are those 1st edition books without alleigence abilities/ghb alleigence abilities such as Everchosen (basically confirmed due to Darkoath), Flesh-Eater Courts (again, basically confirmed with Carrion Empire), Fyreslayers, Skaven Pestilens (beasts of chaos type Skaven book), Ironjawz.
Slaanesh are basically confirmed to get a book with new models and id say at this point Khorne needs a new book due to the scattered rules and faq/erratas making the current book almost useless (daemon warscrolls at least are due to be updated to match the new rules from Wrath & Rapture-all the Hell Blade weapons)
