Welcome to Librarium Online!
For everyone who's been wondering about Apocalypse prices and such things, it's all up for advance order now on the UK GW site.

Roughly a quarter of the sets are listed as being direct only, so presumably the rest of them will be available in GW stores.
Thou shalt remember:
Warhammer Fantasy armies do NOT have Codices. They have Army Books.
