I'd be in for an early PDF version ... it might even get me back into the new era. Mainly I like it because the future is undefined, whihc makes it nice for players and refs alike.
I'm very interested in seeing the content of this book, but I find pdf format extremely inconvenient for anything over a dozen or so pages so I doubt I'd buy it (just like I haven't bought the Gateway pdf or any of the TA pdfs). Is there any way I could throw in a couple extra bucks to get a printed, comb-bound hardcopy sent by mail?
I'm sure you could submit your PDF to Kinko's or whatever your local copy shop might be and have it printed in whatever bound format you like. I'll probably do the same myself once it's out.
