So the Nexus 4, which is just under 2 years old, won't support Lollipop? Considering the device is from Google and not through a carrier I would expect better. No pricing on the Nexus 6 but I would expect it will cost a lot more than Nexus devices have in the past. And at only 1 inch less than their Nexus 7 tablet it seems ridiculously large. At what point is it a tablet that makes calls and not a phone? Nexus Player…
The Nexus 4 has been nerfed since shortly after the Nexus 5 came out - just like the Galaxy Nexus was nerfed just after the Nexus 4 came out. Based on their history, a Nexus device needs to be replaced once its successor comes out, so it's not a big surprise (but still a shame) that the Nexus 4 won't support L.
Galaxy Nexus was going to be supported by Android 4.2 (I was really annoyed that it wasn't!) but the fact that it's not has to do with TI refusing to update their closed-source drivers for their OMAP 4 chip to be compatible with the Linux kernel used in 4.2. By the time people figured out how to update them, Google had given up on providing support. I'm still pissed about that.
