It appears Warner Brothers and TNT settled with the NBA. They were suing the league because they felt their expiring contract contained a clause that gave them a shot to match any new deal. When the NBA didn't give them that shot, WB/TBT sued.
ESPN will sublicense some games to TNT for them to show. They will also give them some Big 12 football games. They will also have access to other NBA content and be allowed to create new shows from that content. But the big one is what happens to Inside the NBA. That will be licensed to ESPN/ABC. So Shaq, Chuck, Kenny, and Ernie will all be on ESPN next year.
