I think it will be a soccer-type game.
The source of the first hint picture is here:
http://www.ci.cedar-park.tx.us/cp/re...e-exterior.gif --It's the Cedar Park Event Center. Here is some info about the Center from
http://stars.nhl.com/club/news.htm?id=450346 :
Cedar Park Event Center -- Fast Facts:
-Future home of the Texas Stars Hockey Club, which will serve as the primary development affiliate of the NHL’s Dallas Stars.
-Multi-use facility: concerts, basketball, tennis, indoor soccer, rodeos, trade shows, figure skating competitions, conventions, banquets, dances, graduations, pageants, celebrations and seminars.
So hockey is the main event there, but I am betting on soccer, since indoor soccer is one of the activities, and the gratuitous references to football players in a post with a picture of Saturn (in the second hint) could refer to a soccer team (
http://www.saturn-fc.ru/en/) or league (
http://saturnfutbol.org/).
Add to this the availability of this ball
