I don't consider myself a complainer by nature. I would be very suprised if they aren't quite sure what it is going to be when they will put in on the market within two months. And they can always place a disclaimer at the head of the provisional feature list. Heck, SketchUp 3.0 had next-edition features hidden in an additional menu that any user could access. It is just that with all the different packages they are offering now, it becoms really hard to know what is the right choice.
