Some speculation from the C.H.I.P 7706 poster that was found in Zombie Hunt, which Thorpe liked before the tweet was deleted.
A lot of parks have been teasing new coasters this year giving the vital statistics of the ride. I'm wondering (or rather speculating and making a straight line from two points) if Thorpe could be doing the same.
We have 4 letters and 4 numbers. My wild speculation is they match up:
Coaster Height 77m. This just happens to be near enough 250ft, which is higher than Thorpe previously sought permission for, but is just 1m taller than Shambhala, and the exact same height as Energylandia's Hyperion.
Possibly the P and the 6 form Project 6. Any new roller coaster would be the 6th large coaster in the park.
The I could either be part of the project name, so for example I(nvestment) Project 06. Or it could be the number of inversions is 0.
It's all speculation, but a 77m tall coaster with possibly no inversions, sounds a lot like that hyper we keep talking about.
