Is there any chances of an official Hot-Uprade App mechanism for iOS devices?

I think the most important feature for iOS native-developers is the Hot-Update(Because it's so hard to force your app's users to upgrade in AppStore), And this is the reason why so many cross-platform technologies are needed . Is there any chances that Apple will issue a official Hot-Upgrade mechanism for this ? And I think it's not very hard to Apple to achieve this .
