I heard from Jon, the admin and lead programmer at Stencyl, that it will definitely not be out for at least two months. Although you should check out
SlickSet. It was created by Jon, and has all the features that you will need to program Kits with once Stencyl comes out, so if you can program in Java, this'll be like a head start before Stencyl comes out. :3
Seriously though, I'll try not to say too much, because I really don't know these kinds of things.
