in addition to the high entry price, a major turn off for me in the past was the inherent choice you had to make based on your dev platform... you could either target ios/android on mac OR android/windows on pc. if they figured out a way to break that barrier and still offer the native bindings... this is huge.

still $999 to get visual studio support though... i wish they would adopt a licensing model like unreal sdk. you can use it for free and you only pay royalties if your app nets certain $ thresholds.
