TB2 is a dead port and it's a fact. Not only for video and music. Animation, effects, and more. It will be a problem in long-term because it can not cool CPU and GPU inside. It will cause meltdown. My school labs have tons of Mac Pro for Photography uses and guess what? Over 30 of them had been sent to Apple for repair. They were full upgraded version. There is no doubt that Mac Pro 2013 is a Failed product. You need to think about overall opinions, not just personal opinions. Just fine? PC can be built for much better performance with cheap price and better cooling system. That's why a lot of people left Mac Pro behind. Im really tired of having a conversation with you because you dont accept facts. Deal with it.
False facts...Literally dozens, perhaps hundreds of Thunderbolt devices available right now. Not sure where you get your facts from:

I don't call it quite dead by any means. Just not used by the average consumer. Its mostly for professional use.
