The problem with that is that if Sabin, or any other X Division Champion in the future for that matter, decides to defend the title rather than go after the TNA WHC, then the concept in and of itself means nothing. Even worse, it winds up making the X Division Champion look like a total punk. There's no real way to build up the suspense of Sabin's decision without himself or TNA in & of itself or the creative team looking look like total fools.
From a strictly kayfabe perspective, the idea of a mid-card champion purposely throwing away an opportunity to win the World Championship, thereby elevating himself to a whole other level in his career, is beyond ludicrous. From a "realistic" POV, one could attempt to argue that Sabin turning down the match in order to rebuild the prestige of the X Division & its title. However, there's no real meat to the argument because, as I alluded to, it defies any degree of logic in all of wrestling to turn down an opportunity at THE top spot. Sabin giving up the X Division Championship won't do the X Division any favors as the mid-card title scene, as a whole, will continue to be atrocious unless TNA's strategy towards it changes dramatically. But, that's the corner TNA has painted itself into.
As for what will happen on the show, I'm at the point where I almost couldn't care less unless some significant changes are made to the X Division between now and July 18. If the X Division remotely meant anything, I'd be more interested in this particular show. I highly doubt Sabin defeats Bully Ray. If he did come out winning it, however, I expect TNA to pull a Christian and put the title back on Ray within a matter of days. Aside from Sabin, there's no other reason to care about or invest in any of the X Division wrestlers. They're doing the best they can with what they've been given, so kudos for that, but it doesn't change that what they've been given simply isn't very much at all.
