Without reading this entire thread I have to say it is ridiculous and I will say why.
First off, the moment you purchase the handset you have bought a device as is, with no entitlement to upgrades, that thought is just absolutely ridiculous. The FACT that the OS developer and equipment manufacturer have committed to improving their products with the PROMISE of updates and improvement does not in any way, shape or form mean it is something owed to you.
I would say just sit back and relax, wait for it... if you just can't find it within you to do so, then there are less generous platforms and equipment manufacturers you can donate your $ to.
