I imagine the evolution of BBC World News as a channel also played into the plans for studios. Initially, the plan was clearly to simply replicate the setup at TVC. This made sense when WN was largely similar to the BBC NC for domestic viewers, and largely comprised of straight news bulletins.

Later on, by the time plans for NBH were further developed, WN had become a channel of focused branded strands. The opportunity was taken, with Studio B especially, to give each programme a distinct “look” and presentation style. This meant the big open space, and hard and soft sides of B both being available to them and flexible, was a huge bonus.

I expect this was true later on, but the decision to drop the two newsroom studios was taken by at least the 2007 plan revisions - really before the brandification of BBC World, so I'm not sure it would have been a major influence in the changing studio plans on that level. Instead, I suspect the key thing in pushing part of World News into B was the fact that most of what used TC7 was axed or moved to Salford - leaving TC7's replacement with little to do all day. That big hole in their flagship studio's schedule, combined with that stretch of BBC World News having a lot of 'prestige' programming in it, gave them, as you say, a solid reason to move GMT, Impact, The Hub, etc. across to B.
