Yeah....... I see no reason to wait to book Jones.
Strip him, elevate Tom and book him another fight.
If Jon wants to fight again he will be given a title shot without delay anyhow.
This waiting by the UFC to get the money fight is a loss leader at this point. Even if they get it they have lost money keeping Tom on the bench.
When Jon fought Stipe and Buffer announced him as "Undisputed" I threw up a little.
The UFC gave Tom the interim shot to save a card. On that day, Jones became a disputed champion.
