Guys I am just going on what I have been told...
Remember when the last satellite was launch they were promising us over 150 channels... what happened?
Look how much new national HD we got from D11.
Either the person you talked to was wrong or they miscommunicated the info to you. The FCC documents clearly show what D12 is capable of. 16 CONUS transponders for 80 channels and other transponders to support 49 spot beams. There is also gonna be 18 spot beam transponders using the new BSS frequency (17345-17700 MHz). What D* will do with it? Who knows.
Now I was just as disappointed with the lack of significant HD expansion after D11 as the next guy. Arguing this is what lead me to stop posting at the other site. But in fairness to D*, 4 of D11's 14 CONUS transponders were used up for existing HD channels. D10 was originally suppose to have only 14 CONUS transponders but instead 16 was used initially. So the channels on those transponders had to be moved to D11. Also the old legacy MPEG2 HD channels that were on older sats at 110 and 119 got MPEG4 versions on D11. So that's spots for 20 channels used on channels we already had.
After that these new channels have been added over time since D11 was launched.
Planet Green HD
ABC Family HD
Showtime 3 HD
Showtime Extreme
Fox Sports South HD went from part time to full time
Sports South HD went from part time to full time
Sunshine HD went from part time to full time
Fox Sports Prime Ticket HD went from part time to full time
Fox Sports North HD went from part time to full time
Fox Sports Midwest HD went from part time to full time
Fox Sports Rocky Mountain went from part time to full time
Fox Sports Arizona went from part time to full time
Fox Sports Northwest HD went from part time to full time
Fox News Channel HD
Crime and Investigation HD
Golf Channel HD became it's own separate channel from the old Versus/Golf Channel HD combo channel.
Comedy Central HD
A channel spot was used to start pushing 1080p movies down to HD DVRs
Yankees Bonus Cam HD
Sports Time Ohio went from part time to full time
MASN HD went from part time to full time
MLB Network HD
MLB Network HD alternate
BET HD
So that's 24 new channels (although the value of some of these is quite debatable and maybe shouldn't have been done - hint moving part time RSNs to full time and a Yankee Bonus cam) plus 20 existing channels being move from existing locations.
So that's 44 of the possible 70 channels D11 was suppose to add. Unfortunately a lot of the remaining space is being used for full time HD PPVs (not the part time HD PPVs that share space with part time RSNs and sports packages like NFL ST and MLB EI) that should be used for regular HD channels and I think D* has some unused space (10 or less) that they aren't using for some strange reason.
Now when D12 goes up either in mid October (not likely) or mid December (more likely since another satellite is going up mid November) with activation probably in February, I remain skeptical of D*'s ability or willingness to negotiate contracts for additional HD channels. Their recent track record in this regard since Malone bought them is bad.
