Hope for a third installment in the Tron series has been floundering for a few years now, however, it seems like the hope for Tron 3 isn't altogether dead. According to Blade Runner 2049 and Suicide Squad's Jared Leto, the film is in discussions.
According to Leto in an interview with Collider, his role in Tron 3 is "in discussions" (as is the film) and the film is currently in its "very early days" and still looking to become a reality.
“It was a huge movie for me as well and I do think there’s so much potential in that world, there so much left to be said," continued Leto. "I’m absolutely game to try to help in any way that I can bring that to life. It’s something that we’re in discussions about and very much looking forward to bringing to reality. It’s very early days though.”
Basically, the film is still where it left off – in limbo.
