Jon Jones isn't a huge PPV draw yet. He may be by the end of 2012 (and in fact he SHOULD be by the end of 2012).
Anderson Silva is the greatest MMA fighter of all-time, but his PPV buys aren't as spectacular as Brock and GSP because he doesn't speak English.
That would be a purist's dream match to be sure, but it's like saying "How many PPV buys would CM Punk vs. Shawn Michaels do?" There's a huge difference between being great and being a draw.
UFC is proving that even with real sports, what draws the most viewers is not the biggest matchup, but the best storyline. All the PPVs they do that have "heated rivals" (hint: it's a work) main-eventing against each other do better business than just flat out great fights with no manufactured animosity, unless GSP or Brock is involved.
