We're not exactly sure how adding a 45th HD channel to the lineup will affect Cablevision's 44 Days in HD promotion, but we're pretty certain the subscribers who have been waiting ages for ESPN2 to finally go HD on their provider won't care. Yes, the poor, tortured Cablevision customers can finally look forward to catching the Deuce in high-definition, as today marks the first time it'll be broadcast as such to iO TV users. You've waited long enough, so without further ado, head on over to channel 735 (and feel free to be extra celebratory this weekend).
