Although no substantial progress has been made on Tron: Ascension recently, there's still a pretty clear case to be made that fans would want to see it happen. Many die-hard Tron nerds have demanded to see Disney give the project the go-ahead, and Tron: Legacy laid plenty of narrative groundwork for future installments.
