My Pro X hats showed up this afternoon. I noticed on the Alesis website that there is a firmware update for the DM10 module dated 8/5/14. I'm assuming that the update includes new settings or the Pro X hats. Looks like I have some work to do this afternoon.
Here is what is included in the box. Two 12" hi hat pads (upper and lower), new hi hat clutch, large spring and round plastic retainer for the spring, rectangular trigger output box (sits under bottom cymbal pad), two new 1/4" trigger cables, two velcro tie straps and the manuals.
