Codex Chaos Space Marines What I Think is Good.

Thursday night at midnight I took out my iPad and went to the iBook store, searched "Games Workshop" and the usual list of offerings popped up but no Codex: Chaos Space Marines.  I waited until 12:15 and tried again but no dice.  So I went to sleep slightly depressed after posting a query on Dakka.  All day the best I could find out was that GW may be planning to release the iBook codices
