I will try to keep this thread updated with relevant information. This first post will be more speculative and become more factual with subsequent edits.
HTC One:
-There are already several ports of the GE ROM to various HTC One branded versions. Tickdroid is one ROM, but there are others.
-HTC will allow users of GPE, unlocked, and developer editions to switch ROM paths.
Samsung Galaxy S4:
-There's a near-complete port of the GE ROM for the unlocked international i9505 model.
-The S4 GE SYSTEM DUMP has been flashed to the T-Mobile variant, making it essentially a GE. This just happened today, so I cannot confirm at this time if it is a full conversion (IE, updates straight from Google OTA). Device ID changes from 919 to i9505G.
-Ports are underway for the various carrier-branded versions in differing stages of progress.
-Android 4.3 has already been leaked for the GPE, and it is stable. It is believed to either be a near-final release.
-STORAGE: GPE has 12.65GB available to the user. A TW model flashed with GPE ROM has 9.72GB available to the user due to partitioning.
AOSP:
-For whatever reason I do not know, the firmware will not be in Google's AOSP repository. The firmware on the device is entirely Google, except the kernel, which is done by HTC/Samsung. Both OEMs released the full kernels prior to device sales, so again, I'm unsure of why no AOSP support.
Updates:
-Google will develop the core firmware, and the OEM will handle the kernel. Point releases (IE, 4.1.1 to 4.1.2) rarely need a new kernel unless the update was to patch a bug in the kernel. So most updates will be quick. Larger releases (4.1.x to 4.2.x) will require a new kernel. Expect a 2-4 week delay (possibly less) between Nexus updates and GE devices. Rumors have the S4 GE firmware update as being "imminent."
