The sparrow case aside, there does seem to be limited prospects for sustaining a business focused on producing high quality apps. There seems to be very few patterns for success; e.g. acqusition, serialization of a single hit game, or a store with an overlay requiring the least possible effort to produce. Obviously exceptions can be found, but the idea that the app environment could be modified to make other types of businesses more viable likely has some truth to it.
