I got this from pinside for those interested.
"There was an update on the premium code. At the start of the video, I say the difference is significant.. well, noticeable is more correct. Things I noticed, sound differences and lcd differences in animation, I didn't notice any rule differences, but that doesn't mean they weren't changed.
http://youtu.be/rG0XfJHcUSwI did get into the settings to see if there was a more vulgar Steve ritchie setting. There is still only normal and family, maybe this will be an LE difference? Steve has eluded to some serious swearing at shows, it would be cool to have as an easter egg too, sort of like the mortal kombat blood code."
