Beyond that, Ice Cream Sandwich unifies "phone" and "tablet" apps (a distinction that already makes much less sense in an era with large, 720p "phones"). That completely changes his inferred dynamics of the Android app stores. I think the Android Market and the Amazon Appstore (and GetJar and Handango and ...) and direct sales from developers will happily coexist for the foreseeable future.
The distinction between phone and tablet apps on android has always been pretty blurry, ICS is about unifying the operating system features, not the apps. Talking about a 'tablet app store' is silly, even ignoring ice cream sandwich.
I agree talking about a "tablet app store" is silly (note the quotes around "phone" and "tablet") since many Android apps scale quite nicely for both form factors and more will with time, but, sadly, the Honeycomb detour confused people (especially for iOS-influenced outsiders).
