Why did Disney forget about Tron?

The question today is why did Disney forget about Tron? Disney seems to have a lot of money to waste on flopped projects and of course their cash cow Star Wars. But this does not surprise me, as Disney does not even care about the fans. They only care about how many gold coins the can quickly make. Well I for one have had it! Either they made Tron 3 now. Or they better give or lend the rights to the film to someone who has the passion to actually make the movie. How dare they tease us with Tron Legacy and the XD cartoon, and then leave us with nothing. CLU said he would never betray me. But clearly Disney has lied to us!
