They've used the "fake newsroom" background for DTL contributions from regions before, it wouldn't be too big a step to have replaced that with the real thing!
Is that location bug an error or are they keying a shot of the NBH newsroom behind a contributor in Wellington, NZ?
The guy who posted it has a different name, job and is in a different place mentioned. It's a trial - probably one of these simultaneous practice runs.
I'll be honest, I prefer the current graphics (with the exception of the horrendous programme title box above the BBC World News logo). I think the new ones are a bit *too* plain.
