Mass production optics companies like Skywatcher would have to learn to make smooth surfaces with no macro-ripple before anybody would take marketing of a dedicated planetary scope seriously. Mass production and smooth surfaces just don't go together I'm afraid.
All you need for a good planetary Newt is an obstruction of not more than 20% and a good primary from a custom maker ( there are plenty of them to choose from ) with consideration of thermal issues in your tube . Thats not so hard.
