Hoax. The wiped clean story proved it in my opinion. There are no provisions in any Android ROM google has released to date that would allow the deletion of the ROM itself. Therefore, a "remote wipe" should merely wipe user data, and google would know this, so why bother doing it?
I'll also point out there was no technical details such as kernel version and the like displayed, and all that was shown was a custom theme, launcher and camera.
Nice ROM all in all though, even if it is a fake.
