Sky has shown very little interest this year in cycling even though they sponsor the GB squad. Even if they did show cycling, it would likely be pushed onto SS3 as a minority sport to make way for bigger sporting draws like football.
I would have thought that the competition to show cycling is between Eurosport and Sky as subscription providers rather than free-to-air ITV4 which has a contract with ASO up to 2013.
Actually ITV4 has been pretty good this year, showing several events as highlights programmes the week after, plus the Tour Series and obviously the Tour.
