The TTK teaser shows the year 1 exotics and some kind of mechanics (ascendant/fusion/thingy) to upgrade em to year 2! The part of the video where they show the exotic blue print pic! At the bottom are the year 1, at the top I think are the new year 2 exotics and to the right the year 1 upgraded to year 2! Or that's how I understand the pic.
