One of our writers (I work for Ars Technica) was at CES and was able to film a little gameplay video on the Pro machine there. Nothing super exciting, but you can hear some of the sounds and see a little of the non-upper playfield ball action.
Better than that though is the story she posted has actual high rez pics of the LE cabinet and playfield, not the little ones that have been floating around today. Just click on them in the gallery view to expand out to full size, and drink in all that goldy gold goodness.
It looks to me like the legs are plated brass and the lockdown and rails and speaker panel are powdercoated.
