Sky says it's part of its plans, but for now it remains Freesat-exclusive. A lot will depend, methinks, on whether it remains a 'via the red button' service or becomes a standalone channel of its own. The red-button approach seems here for the forseeable, and I know Freesat plans to make a lot of that coming up (think Champions League football arriving at similar time to Freesat PVRs).
