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.
I'd like to see them keep the 7" tablet size also. I bought my wife a 7 and it is a great size to pack away for flights and traveling. Just generally a lot easier to pack around.
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.
