I quit trying to guess the timing. I thought perhaps after the spectrum auction, or when Sling TV was launched we would get some info. Sling TV looks to be getting some good traction and it is notable that Dish rebranded their international offering to Sling as well. Global distribution, anyone? Sling may or may not be the launch vehicle, but we will have to wait and see. There is certainly more than one way it could happen.
Like several other old timers here, I have placed my bets long ago and just continue to sit (somewhat) patiently for the outcome.
