HBO will reportedly extend access to its HBO Go streaming service to more cable customers tomorrow. Engadget has screenshots of Xbox 360 and Roku activation menus that show the previously unavailable Time Warner Cable and Bright House Networks logos, along with Comcast and DirecTV appearing for Roku. The site's sources also say that Time Warner Cable customers will be able to access HBO Go on Samsung HDTVs and Blu-ray players, though the service actually rolled out for TWC on Samsung Smart TVs back in February. No mention of specific models was made.

HBO and Time Warner Cable are yet to comment, but if you subscribe to one of the mentioned providers (and HBO, of course) it might be worth trying the activation process once or twice come May 17th. The rest of us will have to wait for HBO to offer its content independent of a cable subscription.
