Android 4.3 and the Platform Developers Kit
So with Android Police and others finding substantial evidence for the next Android update being 4.3 Jelly Bean, not 5.0 Key Lime Pie like we were expecting, let's hope the OEMs have the PDK (Platform Developers Kit, announced at last years I/O) so if they're on 4.1, they can skip 4.2 and go straight to 4.3, and if they're on 4.2, they can get onto 4.3 reasonably quickly.
In an ideal world, the Android 'flagships' from the various manufacturers (HTC One, S4, Note III (when it arrives) Xperia Z/ZL, Huawei and ZTE flagships) would be on 4.3 Jelly Bean (assuming it is real) by the time the next Nexus is announced. Google really need to sort out the update thing...just hope the OEMs have the 4.3 PDK now, and are using it to get 4.3 to phones (I'm looking at you, HTC) ASAP, skipping 4.2 if they're on 4.2.
Sidenote: it would seem that a new Google name/versioning structure is in place. Each x.x release (so 5.0, for example) gets a new name, like Key Lime Pie. But each incremental update (4.1 to 4.2, for example) keeps the name. Another way of putting it: x.0 gets a new name, everything else keeps the name.
