I didn't look at the Spiel pictures until just now. I'm glad to hear that they have it, and this is coming from someone with a laser cutter who can make his own acrylic overlays.
Just this past week a friend got the Scythe expansion and we were commenting on how good those player mats are.
They add so much to the gameplay experience. Eagle-Gryphon Games added them to Lisboa during their recent Kickstarter and Portal Dragon added them to Zephyr: Winds of Change after the campaign during final design. I hope it becomes a bigger trend!
