I can't blame completely for Microsoft for this but... One thing I want to say is Please don't install the developer preview ( pure wp8.1). Microsoft said that all windows phone 8 devices will get wp8.1 it is true but not as of now. This pure os is having some performance issues with the hardware (that is what the firmware is expected to fix). On an high end phone such as Lumia 920, I can experience a lag sometimes. I've also heard that low end phones like L520,L620, it is even worse . So, people who are willing to perform the update please stop there (especially for low end phone users) and wait till the actual firmware is released.
