Hi Guys, I can confirm 2014 Macbook Airs' have Thunderbolt 2. I just bought my Macbook from the Apple Store and looked in the User Guide to be surprised that it said Thunderbolt 2. I personally thought it was a typo until I removed my daisy chain linkup of my 2 Dell U2412H's from my HD6850 of my Desktop and connected it to my Macbook. Then, I saw both my screens mirrored. I thought it was typical of my MBA to do that considering it was Thunderbolt 1. I went to the display options and to disable my second monitor because it was wasting electricity to find that I could extend the screens. I couldn't believe, it worked. Considering that this is only possible with DP 1.2 and Thunderbolt 2 is the only controller capable of DP 1.2 at the moment, I can conclude that this 2014 MBA has Thunderbolt 2. THANK YOU APPLE! Now I can offload my work to my MBA. By the way, I have the i7-4650u model. Will be posting proof in a week or two. Waiting to get my 3rd Dell U2412H .
