We are just two weeks away from Google I/O, so a tease like this could mean that we are going to see Android 5.0 announced at the end of this month. Full version number changes tend to indicate UI updates for Android, and we have certainly seen quite a few leaks that point to design changes on the way for Android, including the mysterious Project Hera. It is also expected that Android TV will be announced at I/O, which further implies that Android 5.0 might really be on the way.
