Assuming it is 15%, you'd think E* would be rushing to get new HD to the air then, especially given that D* adds HD weekly and now our local cable company has the same HD channels minus Voom. If even 1/3 of those with HD left for other options because E* is falling behind, no company wants to drop 5%. Also figure that anybody upgrading to HD at this point would automatically be drawn to D*. With a 15% figure, they are hemorrhaging money at a clip they can't afford. If the figure was 5% or less, they could let it ride for a while and not lose much.
