Disney's Tron: Legacy is about to pass the $300 million worldwide mark, which has the studio close to moving forward with an Untitled Tron Legacy Sequel announcement.

It is said that Disney is "incredibly close to having its sequel announced," although it isn't said when such an announcement will occur. We reported in November that Disney was planning an animated TV series entitled Tron: Uprising, which will debut on the Disney XD channel in 2012. It was also reported last month that the series will take place right after Clu takes over the grid. A separate 10-part Tron micro-series is also set to debut this fall on Disney XD.
