Could you name second bigest Android app store? I think there are at least two problems: 1) average user will not download anything what's not in win8 app store; a) There are extra burden to upload app to store and pass QA process (I think the only exception here is Google). Haven't you heard horror stories about clueless QA people? 2) there are extra warnings for apps that are not from win8 app store (like in Mac OS X). E.g. I find it annoying because I use relatively lot of tools that are not from app store. Again average user might prefer safe way over risky one and it is problem for indie (game) developers.
