Are any of these it?
Docks. Well, only 2 are X but i don't know anything about cars to tell if that's what you're talking about. : )
and here's the smattering they have up as well, it's for all modern motorolas, not just the x but a couple there...

This worries me. The car dock for the Moto X on Motorola's own site is made by a third party, and it only states that it puts the phone in vehicle mode. It says nothing about charging or audio. The rear shot looks good. I can remove the suction cup, and it will fit my ball mount. It appears to hold the phone well, but it is either incomplete, or their description is lacking. Looks like the put the new pages up before they were done changing the site. So there is hope.
At this time I'm leaning towards the Droid Maxx, but if they don't come up with an acceptable car dock, I'll wait to see what LG does on the G2.
I don't care if Motorola has given up on making docks and is letting a third party do it, as long as it is done it right. I'm looking for a dock that fits the phone properly (not a generic clamp), fits my ball mount, or an AMPS pattern plate, and provides integrated power. With wireless charging, the power should be easier to integrate than ever. I can go without integrated audio if I get the rest. My next stereo will have Bluetooth anyway. I was less than pleased at how the RAZR vehicle dock USB charging/audio cable worked with music, but not speaker phone. I sometimes bypass the integrated cable and plug directly into the audio jack on the phone. Shame, I paid somewhere around $30 for the integrated USB/Audio cable in addition to the price of the car dock.
Edit: Yeah, Motorola is rebuilding their site. Droid pages are there, but not linked from the homepage (Google search found them). Also, most of the pages are not rendering correctly for me, and some links don't do anything. I really wish companies would finish re-building their sites first and then post the final version. I'll hold my final judgment of their docks until I can see them, or they get their site finished.
