Ten days ago, HTC announced it delivered the KitKat code for the HTC One Google Play edition, and that it was up to Google to push out the OTA release to users.
Now it appears that the OTA is on its way, as both HTC and Samsung have published the kernel source code and framework support files for the HTC One GPe and Galaxy S4 GPe, respectively. The files contain the open source component of the ROMs for the two devices, that HTC and Samsung have to release to the public, as per their GPL licensing.
