Disney has just confirmed the longstanding rumour that Tron is indeed coming to the Magic Kingdom at Walt Disney World!

TRON Lightcycle Power Run

In the concept art below it is made very clear that Tron will be located near to Space Mountain and will NOT be replacing any attraction in Tomorrowland. This means that contrary to rumour, Space Mountain and the Tomorrowland Speedway will remain at the park for now.

Tron will be open at Magic Kingdom by the parks 50th anniversary in 2021.
