Don't forget the "hundreds" of color illustrations. Seems very glossy hype, but it will be interesting at least to see what they consider as the ten most important symbols on a card. I admit, not all symbols are created equal, and not everyone really, really needs to hunt down the obscure poetry pertaining to the sparrow on the Empress, so some things really can be pared down.
My main concern is that it turns out to be just a "repackaging." I liken this to the "gold" spectrum (all of these analogies are strictly "IMHO," by the way):
There's 24-carat solid-gold bullion - the "real deal": Crowley's Book of Thoth
Then there's 14-carat jewelry-grade gold, "worked" or carved gold whose elegance depends upon the eye and hand of the artisan: DuQuette, Wang
Next, 10-carat gold alloy, cast into rings and such; durable and functional but less valuable: some of the better Banzhaf
Followed by gold plate, just a thin veneer of precious metal: some of the lesser Banzhaf
Finally, "fool's gold," which is where I stick Ziegler
Time will tell where Fiebig lands. Anyone have books to add? I admit I'm not especially current on who has been mining the "Thoth motherlode."
ETA: If this is wandering too OT, please disregard.
