Channel 4 HD Say No to 720p but Yes to RED

In a technical requirement document dated this March Channel 4 HD in the UK state that they will not accept 720p as an acquisition format but will as a slow motion variant and then only from the Panasonic Varicam model.
In the same document Channel 4 also list the RED camera as 'acceptable' for acquisition. HDV can only be used by 'special agreement' and the jury is still out for XDCAM HD and the EX1 model.

Full details are in this pdf, acquisition formats are in section 10.1
