This is a good article on slate.com that talks about Gameday's new Pitch f/x recorders.  The author talks about how this will lead to a ton of new areas for research for baseball statisticians such as those found on BCB.  I thought it was interesting and that you might as well.  

Another interesting note came at the bottom of the article.  Apparently MLB is thinking of putting up cameras next year that will capture individual portions of the field and will try to numerically measure some fielding statistics.  I'd imagine range and speed would be among the measurables.
