Cedar Point I feel like they're going to go big in the next few years until their 150th anniversary. Some of these probably have some reason they can't happen but I feel it could be Plausible.
2016: New Coaster is a definite at this point. I really don't believe the dive machine rumor so I think its an absolutely massive wooden coaster. I can't decide on who the best manufacturer would be, a Gravity Group would be amazing but probably wouldn't track very well in a few years of lake erie winters. A GCI might track a little better but it would be a little more family friendly. Right now I'm leaning towards an Intamin prefab in the hopes that it would last longer and fit the park better. The ride would be on a new midway connecting the dead end near blue streak to the stage near Iron Dragon. A flat ride or two may also come. Coasters start to get paint refresh
2017: Major new water park expansion to bring the place into the modern day. Two slide towers would come, the first would be 4 drop pod slides, 2 with aqua loops, and 2 with out, then two regular free fall slides higher up on the tower. The next would have a water coaster, Tornado and a combo bowl/zero-g wall slide. In the park their would be some more minor improvements and Mean Streak would close down. Paint refreshes continue and new kiddie coaster is added.
2018: RMC Mean Streak opens along with the whole are being refurbished. Complete overhaul of the food stands with some outside vendor coming in. One or two flatrides will come also. Once again, painting happens all over the park.
2019: Dark ride finally comes true and it's built in the back of the park near the new Evil Streak which was starting to fell like a stale feeling area. More minor refreshes all over the park like food and repaints.
2020:Major, Major year. By this point, all coasters and rides will have been repainted and the whole food department is overhauled. The whole park will have a new feel to it, no more black top and shade will be added to empty areas. New lighting packages on all the rides that need it. Two new coasters will come this year. The first will be near the front of the park, a Poler Coaster and the first to top 600 feet. It could be place by Raptor's lift hill or near windseeker. The second will be a more family friendly mack multi-launch coaster to replace the mine ride. Of course, the midways near these rides will be refreshed.
