GPE devices update is still kinda mystery.
OEM say Google handle the hardware adaptation & function updates but Google say OEM will deliver updates themselves.
I think Google will just take care of the entire system update but it is up to the OEM when they want to push the update.
Back to Nexus story,I wonder how long will the Nexus devices will have to wait for the update & how many features will be Nexus 5 exclusive.
I found the whole "Google Experience Launcer is a Nexus 5 exclusive" thing to be a stupid idea.The launcher file itself is mostly dummy file nowdays.Since the Google search is in pretty much all Android devices why not push the experience too all Android devices? It's a good thing if more people use Google stuff right?

I think the official KK for N4 might involve radio updates as well, as happens in the past. Compiling KK looks easy, many KK ROMs already available, but we are not sure yet on the radio, and official LTE as well, maybe not for our region though.
snapdragon 800 has the always on chip to detect the "ok google", so that might make the google experience exclusive for N5. so, full KK experience really depends on the hardware it's running as well, not similar for all.
