The Win8 Store isn't even open to all submissions at this point. Microsoft has only issued a handful of keys to selected developers, which allows them to submit apps. Without this key, you can't even make a developer account. If you don't have a key, you can still develop Metro apps with VS 2011 Beta and test them using the Windows app certification utility that's included to see if the app would hypothetically pass. I suppose this limits the growth of the Win8 Store at first, but I'm still surprised that there are only 99 apps given how many keys were issued. Also, I believe Microsoft is funding the development of apps by some popular app developers for iOS and Android.
