This is actually happening very soon for customers of Sky Sports.
It's all about giving customers more choice about what they pay for which has been out of touch for many years. I don't think its going to be quite as simple or cheap as the Mail makes out. It will lead to inflation in the costs of the Full Sports package, IMO.
Keep eyes open for this incoming soon.
This might be connected with "mailshots" about "free" HD Sports but I have no info about that.
