I actually suspect Jelly Bean could very well be derived from the idea that ICS was just a transition build. ICS merged GB with Honeycomb and ICS is the test subject to get the major bugs worked out. Once Google feels it has run it's course, we will get JB which will be an enhanced version of ICS possibly with more long term support. If JB brings LTS, this could bring Android to a once a year release schedule similar to iOS which then minimizes fragmentation.Assuming it will actually be Android 5.0. Why not Android 4.5 or something? Integrate new features into the current OS for phones that support these new features.
