I wonder if the "app ecosystem" will move towards paid web services that people use on their mobile devices. I know the whole native vs web app debate has been done to death. Many games probably won't run in mobile browsers in the future. Would be interesting if apple's (and other companies') mis-management of their centralized app stores ultimately incentivized developers to move to the web as the "app store" to the extent that one could make a living.

One data point or trend that seems to support the above idea: The popularity of free apps that are monetized via in-app-purchase. Would be great if the future saw more free web apps monetized via app-in-purchase provided by Stripe or similar.
