Something tells me that BBC are planning on going back to the original format of "Oneness" back in Christmas 2016. As for "#XMASLIFE" I'm imagining that, like Brekkie has said, BBC One will finally ditch the awful "Oneness" idents and use the new "OneLife" slogan, which I think suits the channel well. Either that, or these idents are a base of the next 2020 idents.
Also, I imagine a version of that without the cat will be used for news, perhaps the odd persons feet/legs passing by but otherwise completely silent or ambient household background noise.
