I'm definitely going to live with being a year behind as well. But according to Dish's site, HBO is $16/mo, while Showtime is $13. That's still more than I'd care to pay for the one show I want, but not by much -- if they run 4 episodes, and I had to pay $2-3 for each, that's $8-$12 from me, just for one show. They wouldn't get that all year, of course, but as it stands they're getting squat, so it would be a net win.
I can only presume that at some point there will be enough cable cutters that they'll be forced to change this model. I imagine they're getting some pushback (and maybe a kickback?) from the likes of Dish and Comcast, though, because at present you have
to buy an otherwise-useless cable subscription just to get the right to pay again
for HBO. But still, someday this will change.
