I wonder what that would mean for most of us given we live abroad. The past few seasons, between Sports Plus and Antenna we had access to every PAOK game. At least in Australia, I think the US was the same as well.
Maybe a move to Open will mean a better quality of picture, but I think that is more a satellite thing than a Greek TV station thing. The Satellites they use to pick up the channels have to be at least 50 years old.
