i think it would be great if the park got a new coaster in 2016, but Imo, they don't need it. Everytime I go to the park with friends, I ways get asked, "what is there to do besides coasters?" And saddly, there isn't much.
While most people aren't excited about looping dragons, I think it's one thing out of many the park needs. The way I look at it is flats can only help parks, not so much hurt them. Sure capacity isn't great, but if worried about it, don't ride it if it has a long line. And if anything it's only going to draw people away from the other rides you would want to ride.
Personally I would love a flat package of about 3-5 family and thrill rides. The park can work on filling in the empty spots around the park, boost attendance, and make money to buy the new coaster for 2017!
