Can anyone explain why they're releasing KotS BEFORE the rules? I know it includes a little play guide, but why do that? Obviously a play guide won't include all the rules necessary for play, or it'd be one big "quick start" guide. So why bother? Why make it so that I either buy it and wait a month or two to play it or DM it right away and then can't level the characters until the rules come out, causing consternation? I see absolutely no upside. I mean yes, I'm going to pick it up early, but mainly to look at it and drool over some new rules. But I can't imagine it's just a big preview...
