Seeing the 5 presenters on the list, it's obvious the BBC is intending to retain the branded shows to the newly merged channel. Why they would waste time in performing "screen tests" where the fate of the NC presenters are already doomed, the presenters of the four branded shows already have their seats secure:

Matthew Amroliwala (Global)
Christian Fraser (The Context)
Yalda Hakim (Impact)
Lucy Hockings (Live)
Maryam Moshiri

Funny enough the presser from the BBC states "The five chief presenters announced today were recruited via a competitive interview process in accordance with BBC HR procedures."...

Recruitment process my foot! this is basically hanging everyone on the News Channel out to dry and allowing World to win out!

Yes, but it's no surprise that World has 'won out', World News makes the money. There's no money left for the News Channel, despite what you might want. So if it wasn't for World News, the NC would be closing and there would be nothing to replace it. 
At least, thanks to World, there will still be a semblance of a News Channel from the BBC on air in the UK. Yes, it's sad to see experienced and well liked presenters lose their jobs, but don't blame the BBC for that, blame the government for 12 years of cuts to the license fee.
