Comcast is stepping up its busy HD rollout (and channel squeezing) schedule, with several new channels spotted today in the Detroit and Chicago areas. Science HD, Disney HD and ABC Family HD are probably in your local channel guide -- Discovery HD is now listed DSCHD, while Disney is DISHD, confused yet? -- and word is they should hit many other areas Wednesday. Posters at AVSForum indicate more of the 3 channels-on-one-QAM compression tactics are afoot, take a look and let us know if having High School Musical 2 in HD still satisfies.
