I saw one about a week ago, I train with a TT rep and he has one. Don't know if they are on the open market yet. They are pretty nice, the transmitter is slightly smaller and lighter. The collatr it self is a little bit smaller as well. Best feature and improvement as I see it though is that the collar and transmitter have a charging cradle and can both go from dead to full charge in 2 hours. They have also changed the batteries as well so you can put both on the charger everyday when you get back in and never end up training and have your collar die part way through the day. I may see him training today, I will ask him when/if they are going on the market. Should be anytime I think.
