I'm surprised at the lack of a 25 fps mode too. It could be down to hardware restrictions, such as the write rate to the CF card, or limits to what the processor can cope with.
I wouldn't be surprised if it turns up in a firmware release. If it's bound by bandwidth to the card then it'd be possible to reduce the JPEG quality slightly for 25 fps, and keep the data rate constant. If it's processor bound then it shouldn't be impossible to optimise some of the inner loops and squeeze out an extra frame per second.
Sure, 4K might not be necessary for PAL broadcast, but it could be useful for compositing, or even downsampling to 1080P in the edit stage.
