I was thinking about 2016 recently and I realized something. Raptor was built 4 years after B&M's first coaster was built. So, if they were gonna continue that trend an RMC could be built in either 2015 or 2016. If they start construction on Iron Streak at the end of 2015 it could open in 2016. That would leave a big enough gap for another expensive coaster to be built in 2020 for the 150th anniversary.
