ESPN had a presence at this CES like no other we've witnessed from the sports network and the last of the four letter network's big events was Top Rank Boxing live from the show floor. The event drew quite a crowd and the 3D quality didn't disappoint. The crew was using a Sony HDC-P1 camera system with 3D rigs by the Pace Cameron Group all sent through a Sony MVX-8000x production switcher. If you didn't catch it live on ESPN 3D, we're sure there will be plenty of opportunities to catch the 3D reruns.
