Thanks for asking Matt and those of you that sent pm's and texts. They were able to get out and probably saved a few other people from making a mistake. Normally Georgia Pass is a fairly easy trail but the recent snow and some wind put a nice coating of ice and some fairly deep drifts on the west side of the pass. With the right recovery gear, tires or chains it may not have been a problem but for more stock vehicles it was a challenge.
As it turns out, since they were just on the other side of the pass, a couple of other vehicles that were ahead of them the next morning saw the abandon cars and decided not to proceed. Instead they parked at the top and ended up helping them free each of the cars. A little snow melt on Sunday was also very helpful.
So, all vehicles made it safely home with no damage, just a night out in the cold.
