In no order
1. Breaking the 400ft barrier just 3 years after breaking the 300ft barrier
2. The 4D coaster
3. 90 degree turns on a wooden coaster
4. The hydromagnetic water coasters
5. The Intamin plug n play wooden coasters
6. The rapid construction of theme parks being built in China
Don't know what I was thinking when I mentioned breaking the 300ft barrier earlier.
