I think one of the major road blocks in X-Ball's way is actually television itself. I havn't had the chance to actully watch an X-Ball game, but if it's anything like watching pro's, it'll be a difficult thing to translate to the small screen.
All other televised sports have some sort of centrality to them. Whether it be a specific contestant (like skaters in the x-games) or a ball (like basketball, football...) which the players congregater around.
I had the opportunity to see my first tournament at AC this past august. I found that it was difficult to really watch the game, even from the 50. I wanted to know what was going on with the other side and some stuff that was going on right on the 50 that I couldn't see because of the various bunkers in the way. Granted, if X-Ball were to be televised, they would have better vantage points or more camera angles to show the action, but even with these solutions, it really seperates the spectator from the sport.
The other thing that i noticed while watching was player identification. In other sports, it's relatively easy to spot your favorite players, whether it be by the name/number on their back or their face. Since paintballers have to tuck so tight, it's really difficult to identify who's who. Of course, this could always be solved with different jerseys and/or announcers. Unless you're looking at them from the right angle, you still wouldn't be able to identify them yourselves.
