As with everything Freesat, they're being frustratingly vague. There are rumours of Channel 4 HD being available on Freesat once its Sky-only exclusivity ends in October, but we've heard nothing else. Proper BBC and ITV HD channels would be a start (oh, and PVRs)
I agree - fustratingly slow and no information. I am itching to move away from Sky (very basic subscription - no HD) to Freesat but only when there is something worth moving for.
