No, the Game Masters Toolkit is going to be released without benefit of a Kickstarter. I was able to pay for the art and editing with the profits from my other projects.
My philosophy on this is that I don't want to go to the Kickstarter well too often. If I can put a book into print on my own, I'm going to do it. I couldn't do that for the Bestiary because there's just so much art needed for the thing, the economics just forced me to.
It is currently scheduled for a May, 2013 release. The GM Kit option was largely included for overseas backers who want to be able to combine the shipping on the books. If you don't want to have to wait to get the book in your hands, *don't* pick that level. Just buy it at http://RPGNow.com when it becomes available. (An announcement will be made here.)
