All those things (plus 8 color-changing LEDs, chrome pony emblem on speaker panel, painted metal bottom arch, and action button on lockdown bar) are shared by the premium and the LE.
All three (pro + premium + LE) get different cabinet art, different translights, and different cars pictured here and there on basically the same playfield.
Only the LE gets the totally new cabinet material construction, plus:
5 backbox flash lamps
illuminated speaker surrounds with laser-cut hexagonal grills
shaker motor
color-themed metallic powdercoated armor, legs, hinges, and front molding
designer John Trudeau's signature on the playfield under the clearcoat
serialized number plate (on the speaker panel) + certificate of authenticity
Maybe once we see it the LE's "unique satin glow brushed aluminum finish innovative new cabinet art process to give the car (on the sidebox) a three dimensional look and feel" will make up for the lack of a mirrored backglass?
