I did indeed not get a notification.
You are right, as of now, Motorola are not developing their own special hardware doing things like the always listening features.
Yet, they are the only ones (I think) who are implementing this feature. It still stands out, just like their awesome active display.
Another thing they are doing is offering a very much vanilla Android user experience and that is something I particularly like them for. It's just something you're not really often seeing in triple-A flagship phones (not speaking of Google Play Editions, though).
I just like the way they implement their software features (which partially depend on hardware features) and that is what really differentiates them. They may not have developed really new features for the new Moto X, but still the features they adapted from the OG MX are outstanding. So IMHO there is no need to change these. Why bloat the awesomely clean user experience?
I agree. While some features are not entirely original, it seems that Motorola is LISTENING to what users want and incorporating those features into their phones. Some features on some phones are gimmicky. In contrast, I find the features that Moto is pursuing eminently USEFUL.
The vanilla Android experience and using Google Play apps to help customize the Motorola phones allows the Moto devs to QUICKLY update the features on our devices.
I LOVE LOVE LOVE my original Moto X, but I have to say that I really like where Motorola seems to be heading with the customer requested features, the customization options, and the well-thought-out (and aesthetically beautiful) accessories. That said, I'm definitely "in" for the new Moto X.
