If the rumors are true, it appears the Tomorrowland Speedway will soon be history and TRON Lightcycle Power Run will be replacing it at the Magic Kingdom.
Having said that, rumors are that the Speedway will shut down sometime next year and TRON would debut in 2021, the Magic Kingdom's 50th Anniversary. TRON Lightcycle Power Run opened at Shanghai Disneyland last year and reaches speeds over 60 mph.
The official announcement is expected to come this weekend at the D23 Expo.
