I'd predict it will launch at the same time of the Merger and Rebrand. Which I would assume would happen at the same time.

This would've been my guess, but we haven't seen any movement in terms of studios at NBH which is tipping me away from thinking there'll be one big co-ordinated relaunch. Though, of course, they might planning a BBC World News 2008 thing with regards to the merger and have the new studio delayed for several months after the rebrand (though I can't say I'd be thrilled with the new channel launching in Studio C, which, while not necessarily showing its age, has been used in a fairly unflaterring way in recent years).
