If a license runs out and they want to make more, they will. In the past, they've said many titles "are done" and "we no longer have the license" only to eventually run more. They can renew the license, get orders from distributors lined up, and get the line ready for Tron again if they want.
I'm guessing you'll see something like a Tron SE run sooner or later. High res decals, normal translite, LE ramps and playfield, etc.
