Yeah, that is really old (from last summer I think) and never panned out... There was no Moto X for 2016, the 2017 model is the Moto X4.
Honestly, there is no Moto device that really replaces the X Pure with similar features, you really need to move to another device or "downgrade" to a Moto G5 Plus or G5S Plus, which although a downgrade on paper I found to be a great upgrade other than the front facing speakers... Pretty nice to get 6+ hours of screen time on a single charge or 2 days of moderate use.
