GameInformer points us to the Twitch.tv livestream channel of "PtoPOnline," which recently streamed over an hour of gameplay from Star Wars: Battlefront III. The two videos, available here and here, show several different character types, levels, and situations, including space combat, hero mode, and good old-fashioned stormtrooper-versus-Rebel firefights.
As GameInformer notes, the livestream channel belongs to Past to Present Online, a website that "specializes in the coverage and streaming of pre-release games, betas, and cancelled projects, like Battlefront III."
