Recently Black Library changed their site (a terrible change IMO, but that is a different story). Browsing tonight, I have come to notice something kinda crazy
You can still buy Warhammer Fantasy Battles and all the End Times books.
Yes, you read that right... you can still buy WHFB
They may only be digital. However, there they are, for sale. And at a significant price reduction ($32.99 for the core rule book).
Now it may have still been this way on the last site, but I don't think it was. Correct me in the comments if I am wrong.
No army books unfortuately, but I don't think that means there won't be... they do have several battlescrolls up after all. Maybe AoS isn't the unheralded success they hoped for.
There is this disclaimer "Warhammer: Rulebook is designed for use with Warhammer: The Game of Fantasy Battles. That game system is no longer supported, but this title remains available for those who want to recreate the epic battles of the lost world. To continue the war against Chaos in the Mortal Realms, check out Warhammer Age of Sigmar."
But when has GW EVER sold old rules... sure this is digital and of no cost to them. It could just be a money making ploy, but maybe, just maybe, it is a little bit of back tracking too.
