The official Google TV Team's Twitter revealed earlier this evening that Sony has begun releasing an update for Google TV devices. Evidently, the update includes performance enhancements for Chrome (chiefly concerning start-up time), and the ability to watch 3D Blu-ray movies.
If you're the owner of a Sony GoogleTV, the ~260MB update should be automatically rolling out any time now, but just in case yours hasn't shown up yet, you can go to System Settings > About > System Updates and pull the update manually.
