Maybe he’s super excited of WBR on the new shiny bbc news channel ?

That was my initial guess as well, but then I watched the video in the tweet after the suggestion by @Moz. In the video he is taking about business news during Breakfast.
Here is the transcript of his speech for those who have been reluctant for a while to press "Play":

<...> I'm delighted to say I am back here, at MediaCity, if you hadn't guessed. I'll be back with you on Breakfast, I'll be on a sofa, tommorow morning, Sunday morning, so very much looking forward to that. And then I'll be bringing the business news on Monday, Tuesday, Wednesday on Breakfast. And Monday in particular, I'm really, really excited about. I can't say too much just yet, but it's a big deal. Monday is a big deal. I don't know, might give you a bit more of a clue tomorrow, on Sunday. But, anyway, join me tomorrow morning. <...>
