Quoted from Shapeshifter:
Or maybe it is the LE's that are not doing so well? Mustang LE was a bust. You can still buy STLE. If Stern ditch the premium they know LE sales will rise.
The risk of offering both LE and premium is that people can sit back and wait and after a while the 'gotta have this new shiny toy feeling' vaporizes.
Wouldn't surprise me to see just pro and LE for WD. Then if the LE sells out Stern can introduce a premium AFTER the LE has sold out.
For the current prices, the LE better damn well offer something so cool, you just say "eh, F-it, what's another few bucks at this point for that extra shit". That's how they got me on Star Trek. I was gonna just wait and maybe get a Premium, but the laser cut & lit/animated rails (which also light up on the inside of the cab) & lit Starfleet insignias on the backbox totally sold me. Those are sexy additions that you just can't add to a Premium. Plus - shaker built in & the other LE specific stuff sealed the deal.
Mustang is a tough sell in the first place, but the Prem/LE didn't seem that compelling, and the art on the LE is pretty terrible....no cool rails, no mirrored backglass. Plus - the Premium was actually the one that had the unique playfield (Boss cars). Mustang was just a weird release in many ways.
