First off, thank you for splitting into two books. I picked up the Pathfinder rulebook (575 pages) last year and it's just a hassle to deal with a book that large (I tend to doze off when reading in bed and nearly brained my wife with that thing).
Second, have you settled on a price point yet? For group play I would like to have more than one core book on hand (I don't like sharing my rulebook which is likely to have notes written in the margins, etc), especially for the character generation portion. Pricing may make this difficult so the more notice I have, the more likely I am to be able to talk another player (or myself) into picking up another copy.
Third, there are several of us on the Gen Con forums anxiously awaiting a chance to play this game. Is there any chance of the preorder going live before Origins? If so, how soon would this be likely to happen?
That was spooky...no sooner did I finish this off then I get a twitter about the new blogpost with all the answers.
