This actually popped up in my Google Now news feed yesterday (I know nothing about how reliable the source is):

I would love a refreshed Nexus 5 if it were available on Verizon. I am sorely tempted by the Nexus 6 as it is, but even as a Note user I find it to be a bit too large. This is still solidly in the rumor category it seems.
That article is speculation heavy. Here is another one that says that LG and Huawei will each build a Nexus this year, one a tablet and one a phone:

It is debatable who I would rather have build the next Nexus. On one hand Huawei makes their own SoC, and its on a better process than what Qualcomm sells. It would be nice to have a competitor for the S6.
On the on the other hand LG is preparing a fantastic camera for this upcoming G4, which would be nice to have in a Nexus. Plus it seems like every time Google makes a new Nexus with a first-time Nexus company there are build quality issues. You got to hope that after two tries LG has it down.
The big question for the G4 is the 808 vs the 810. I could see the 808 having an advantage because two fewer "big" cores means less throttling, but the 808 has a worse GPU than the 805! That means yet another LG phone with a ton of pixels but not a ton of GPU power.
If the Nexus really is based on the G4, and it has a 808, than the 6th Nexus would have a more powerful GPU than the 7th one. That would be crazy. It also might be unavoidable, as Huawei is putting crap 6xx series Mali GPUs in their SoCs (like so many Chinese companies do). The real dream is a Huawei Nexus, but as part of getting that contract they have to make a SoC for Google that combines their best CPU combo with a 7xx series Mali GPU.
