Why don't you guys just update manually. The process is very simple....
While you are on wifi, turn airplane mode on. Go to Settings - apps - all and look for google service framework (something like that, im spanish), and press delete data (it is possible that you have to do it twice untill it is fully deleted). Now you just have to put airplane mode off and wait untill the ota appears.
Just thoughtI would post up a bit of imformation. Tired to update my rooted device and it came up with an error. It also errored when I tried it via adb sideload (but this told me why).
My Fix was as follows:
I had installed the ASOP browser and renamed the BrowserProviderProxy.apk and the BrowserProviderProxy.odex. When I renamed these back to the original name, the update worked. I used adb sideload, but I would guess that the update via OTA would also work.
