I'm feeling exactly the same, but since they appear to be keeping around the N5 I have my hopes up that next year there will be a new similarly sized Nexus.

Also, while Google's specs don't list wireless charging Motorola does: https://www.motorola.com/us/Nexus-6/nexus-6-motorola-us.html...

Haven't been able to find info on whether the Nexus 9 supports Qi as well - but again I'm disappointed with the increased size over the Nexus 7 there.
