Hi Pals..
An advisory note is that until the release of the firmware by region has been officially released - with its intended fixes, i guess its better to wait.
Firmware releases at times may be blanket releases (universal) and may at times be localized(targeted at certain hardware).
Usually firmware releases are pre-tested internally before they take the trouble to announce it publicly and have an official download site for it.
Having spend $$$ on you camera, I'm sure you do not want to get into a situation that let you know that the Firmware that you have uploaded was not for your system and you do not have anyway to revert back. These cameras looks the same externally but internally, you may have variants given the different shelf variants they have out there.
So my advice is to hold on and do not rush to upgrade your firmware.
