After so much doubt on this issue, first Wired said it did, then phandroid confirmed it did, then people speculated it really didn't, we finally have word from Google.
First Impressions Of Google's Nexus 6: Really Big, Really Beautiful [Update]
"After some confusion over the seemingly inconsistent tap-to-wake functionality, I reached out to Google for official confirmation and was informed that the Nexus 6 does not include tap-to-wake functionality. It would seem my review unit responded to tap-to-wake simply because of the very slight motion caused by tapping the device, not because it's an actual feature of the device."
So there you go, confirmed by Google. I have to say I'm disappointed by this, since its tap to wake/sleep is a great feature and I love my G2 due to it.
The Nexus 6 does have 'lift to wake' but apparently its not very sensitive (otherwise phone would turn on all the time with any movement) so its not a substitute.
