I can't say with certainty, but my understanding is that once you buy the license (as BhTV has already done) you can keep using it without further cost forever.* Bob did mention that there is cost to rewire vBulletin to the comments each time there's a redesign. And I suspect the reason they abandoned vBulletin this time was because BhTV was in financial dire straights at the end of 2011, and there simply wasn't money to do the work. Consequently, they turned to the free and easy to use Disqus -- just so they could continue providing something
Of course, I might be wrong. But this is my best guess based on what Bob told us in his last Commenter Klatch and the other comments he has posted.
If I'm right - that the decision was made out of financial necessity - there may be hope that Bob will relaunch vBulletin later.
*Unless you want to upgrade to a new version later. But this version would suffice for quite a while, so that is not a factor.
