I am tempted to upgrade my Nexus 4 so have been looking around at replacements.
Unfortunately, one of my motivators to upgrade is to get hold of Marshmallow 6.0, and there aren’t many options out there at the moment for a pure Nexus fan.
The Nexus 5X and 6P are the only phones shipping with Android 6 right now, but both are too big for my taste.
Perhaps we can hold out hope for a Nexus 4X?
I’m also considering the OnePlus X or maybe the ZTE Axion Mini.
