The LTEvo is slated for a Sense update with Blinkfeed for example. They maintain support, this is the Butterfly update after all, they're just slow.
They just didn't used to be.
BTW, I can't trust things to non-local storage and I like not being shackled to a laptop.
PS - Of course, Jellybean 4.3 is about to be announced, so even if they bring out 4.2.2 next week, there will be much upset in the land.
