It is more a generational thing that has to do with the current Windows OS.
First is the trend in Windows
(XP) = perfect / (Vista) = weirdness / (7) = perfect / (8) = weirdness / (10) = perfect / (11) = weirdness
Second is Stardock builds new stuff every generation
Windows 8 = fences 2 / 10 = f3 / 11 = f4
Lastly is demand for stardock products
8 = high / 10 = low / 11 = high
This is why there is new stardock products being pushed and with higher demands there is also more wants as to what their software does so that means higher prices.
