Could it be World's new set? Looks a lot like the current one, it has all the same elements. Plus if they're moving before domestic it would make sense to already have an almost finished set.
But then again that seems like a real newsroom behind and World is supposed to be in a closed studio, if that's correct.
Courtesy of 'thegeek' a few pages back:
The print edition has a schematic which shows the following:
Studio A: Virtual Reality
Studio B (Big Flexible): Newsnight, World News, Marr
Studio C: World News
Studio D: BBC London
Studio E: News Channel
E is in the lower ground floor, with the newsroom view, the rest are in the sub-basement.
Is there a newsroom/ office area 'sub-basement'? Because if there isn't, this picture doesn't fit with the above list. It's clearly not Studios A or B (it's effectively adapted office space, not something I'd describe as 'big' and 'flexible'), but it's anyone's guess which of the others it is. I'd always assumed Studios C and D were proper studios, though, and it doesn't look like the '
Studio E' that's a squared-off section of the main newsroom.
