The only drawback I can see is the variation in equipment across the regions - though that's due to change. When you look at the handover at the end of network bulletins you notice the differences.

SET looks like it's being produced on a 2002 miniDV camera connected to firewire in webcam mode.
Midlands Today looks very yellow (initially I thought this was a lighting issue but it appears to be a racking issue since they've upgraded their cameras, the writing on the pillar is off white - it's even worse when they use the PTZ that's mounted to the wall, where the framerate goes mad and everything has a yellowy green tinge).
Points West looks like a fog has descended on their temporary set.

Slowly they're getting there, and hopefully by the end of next year they'll all look the same (as intended, the documents that go to each site seem to be built around getting the celebrity squares right - I imagine they want an entire column of regions to line their pillars up to demonstrate which region is which).
