It looks that way. There have been rumours of an OS6.1 Lite possibly becoming available for current devices, but I personally doubt that will ever happen.

Why would he wanna do that? To decrease his battery life and get a bug here or there?
I'm running that hibrid and agreed its fabulous. My battery life its about 30% better, faster load, I don't see that damn clock barely anymore, my memory leaks 2-3 % with a whole day of really heavy usage...so before talking I would invite you to try it. (please follow the installation instructions if you are willing to give it a run)
