There's actually a link somewhere to a page[0] that, all the way at the bottom states the price as USD$25,000 for a "Commercial License, yearly renewal".
However, the license specifically states that you cannot use it for sports. I wonder if they singed a high value exclusivity agreement with someone in that space, or if some such company funded the research originally...
"The non-exclusive commercial license cannot be used in the field of Sports. ("Sports" shall mean any and all athletic competition between individuals, groups of individuals or teams.)"
