OK, with (so many) screaming for 24/7 RSN's...E* is NOT going to suck up MORE CONUS HD bandwidth for 5 HD channels that have (very) limited appeal.
You AND myself may like them(& I actually do myself)...but that still does NOT mean they have wide appeal, sorry
As far as CAN they even (legally) offer them in HD...I am NOT 100% sure they actually can. Does the latest law that allows for supers, specifically address this? If it doesn't, they many very well NOT be able to offer them in HD - I don't think anyone can provide concrete evidence either way.
On the blackouts, agree w/Geronimo; offering them in HD is only going to call MORE attention to local stations, (& NOT just CW/MNT affiliates, BTW) requiring E* to do either individual show blackouts (which they will NOT do) or having to restrict their sale in some DMA's even MORE than they already are.
Bottom line...I can 100% GUARANTEE you supers in HD is NOT ever going to happen, period - be thankful they are still around AT ALL!
