Yeah my device is ready.. Hehe as soon as the ota drops and as long as I'm home when it does I will update the RUU.The OTA will include the firmware so you don't have to worry about that. If you are on GPE with stock recovery, everything should be updated.
Now this is optional, but one thing I will do after the OTA is do a restore to factory default because it's fun, and because I want to start fresh.
I'm sure someone will come up with an Android L RUU the same way we have a 4.4.4 RUU now.
I don't know why exactly we weed to run a manual firmware installation twice for it to work (I'm sure the answer is easy to find), but we don't need to do that with an OTA
Edit you have to run it twice because the first time it updates the bootloader.. That's why it reboots the phone back into ruu mode to load the updated bootloader.
