This is 'normal' with Western Legacy, formerly Dartwest, Publishing. Books are announced and pre-orders are encouraged, then you get your book when its ready, sometimes quickly but ususally after a fairly long wait. Once you know what to expect its not a problem and according to their website the publishers are doing away with pre-ordering from now on and books will only be announced when they're ready and will be sold on a first-come-first-served basis. Ther Class 22 booklet will be followed in due course by a full sized hardback edition in the style of their Class 52 series.
