From the above article:

"Sky has until the digital switchover in December 2013 to commit to digitalising the four analogue networks shelved when its analogue channels were pulled in March last year. After that it has another two years to implement plans. But Sky TV chief executive John Fellet tipped a decision before the switch.Sky was also considering capacity from digital terrestrial being combined with its digital satellite TV operation to allow more channels.

Fellet said the other option was for Sky to return the frequencies to the Crown. But that seems unlikely given the strategic advantage they give Sky over Freeview."

 

Interesting stuff - if they have 4 UHF networks, there's a huge range of options for them - subscription HDTV, free-to-air "sampler" channels to attract people to the subscription service, maybe even moving Prime to a less-cluttered mux so it can go HD???
