Just a reminder before this gets a bit (more) allover the place. Please keep this topic to Alton Towers and Project Horizon only. We have dedicated topics for other parks where the likes of Chessington can be discussed.
As a reminder, we're happy for sensible speculation about Horizon for the time being and if that includes RMC that's fine.
However, on a personal note I'd ask people to seriously consider the scale of the ride in this announcement in comparison to the throughput which would be required for what is very likely to be a secret weapon at Towers.
