Xbox have announced that their Business Update will not actually be a brief message or small video, but will actually be part of their Xbox Podcast. The video/audio will be released at 7am on February 16th, AEDT.
There is no telling how much of the episode will be dedicated to the event, but given that the three Xbox leads are going to be on it, I suspect there is a lot to discuss. The video version will be available here, the audio version on most major podcast platforms.
