So bbc world news coming back ?

No.

And it makes much more sense this way. BBC World News was always an unhappy compromise between the 2008 rebrand's attempt to prioritise the BBC News brand and maintaining the then familiar and commercially useful BBC World name, but that doesn't matter much any more as BBC World is but a faded memory (if that) for ordinary viewers. Plus, you'd just be back to a situation pre-merger where - because the majority of programming is simulcast - BBC World News actually ends up hours without being namechecked. A single name obviously works better for two channels that share a lot of output.
