Could well be the one...
...to tempt me away from the Nexus 5X. I'm currently using the HTC One M7, which is looking long in the tooth. I had hoped to escape the atrocious update schedule offered by HTC/Three by switching to Google but if this has quick updates then it might be worth holding fire till its release. Hopefully it will have a card slot to bump that 32Gb flash up a bit.
