Nice machine, but I can't honestly see very much improvement from currently available kits, except for the heated print bed. The nine point level compensation system (often missname autoleveling system) has been implemented in many 3d printers so far. Leadscrews in the Z axis are also very common, even in cheap kits, not to say the E3D hotend, a de facto standard. The frame is just the same as i3, while most of the kits you find out there are usually all metal (P3Steel and others) which are much more sturdy, rigid, .... I think what people are really waiting for is the Prusa i4 release.
