Is a third TRON film still happening?

Didn't TRON: Legacy do really well at the B.O.? I thought another sequel was coming but haven't heard anything in a long time. I really love that whole world.

IMDb lists it as "in development"

I read stuff that said Kosinski was also going to remake "The Black Hole" - but I haven't seen anything about that in a while.
