Worlds of Fun did it. Plus, Kings Dominion doesn't have Millennium Force (look in the background). I discovered the picture, and I'm helping to debunk it - the only place where KD might put a hypercoaster is as a Hurler replacement, and that just got retracked within 2 weeks and new trains at the beginning of the season. Look for something in 2017. The only parks that we know are getting something are Cedar Point (the email-known as Divegate to the KD faithful), Canada's Wonderland (land clearing+survey markings), and Carowinds ("big splash in 2016", Thunder Road closing). There are no leaked plans, trademarks, survey markings, or a hint during a press conference to indicate that 2016 is KD's year. Expect the Shockwave removed with a thrilling flat ride to replace part of its land for 2016 while the land around it gets prepared for a huge B&M in 2017.
I don't see Millennium force anywhere in that image. Also, Worlds of Fun has all of their rides. I think KD will indeed get a coaster in 2016. Cedar Fair goes through a cycle when it comes to their bigger parks, and KD is next in line.
