I think what is happening is that the current state of the phone is not so good and that the incremental improvements from birch to dogwood will not cut it either so they are pushing most folks to evergreen in the hopes that they have worked out most problems by then. As a result, probably releasing a very small number of b through d. Wouldn't be surprised if they try to push or encourage folks to wait for next years version. Not trying to be negative. Just trying to figure out what's happening...
