I'm actually predicting that Cody beats TJ, then calls out Mighty Mouse and beats him as well. Would be epic!
To answer your question though, he does seem to be more interested in fighting Garbrandt than fighting Dillashaw. Before Cody lost his championship to TJ, he called out Demetrious first, and Dana shot the fight down saying that Cody needed a couple title defenses at Bantamweight before he'd be interested in booking that fight. But I remember DJ being all for it, and without any of the same type of money demands that he would later try to negotiate with TJ. Does he see or sense something with Cody that he thinks would be easier to exploit than with TJ? I dunno, but it's possible.
