@ Desert Aviator
Can you ask your contact for more info to elaborate? I have a direct line to a friend (a director) in Mnet, but I don't know if he'll tell me anything (if it's going ahead it'll be sensitive info for the moment)
Closing C Band is a big issue, because all of Africa (excluding S. Africa) runs on C Band....
If Mnet have made an agreement with satellite operators to shift to Ku Band, then it's entirely possible they will close C Band. But this undertaking costs tens of millions of dollars to achieve (and I don't believe Mnet have that funding to hand right now...)
