I'm actually unimpressed with the "new" channels...we did get regular CNN back. Also have Bloomberg and HLN...also Al Jazeera Int'l...still have BBC World instead of BBC America...and FOX is back (on the regular system (channel 75) it had changed into a pay channel), and Showtime is back (was channel 61). It seems the majority of additional channels are Spanish Language.
As a bonus, there appears to be some digital music channels, but I haven't checked them out yet.
Also, if you have a hi-def TV and use the s-video connection, your picture should be noticeably better than before...
