Informed guesses, not something I would be willing to do.
Both will have their own reasons. Ian tweet said might have an announcement today or Saturday?
Jesus, we know it's Monday at the latest and he only left out the Sunday!!
The vibes have been positive for two weeks but I can assure you not even some of our most senior media people have felt compelled to even call it in private to trusted go betweens.
That goes for earlier today also.
I'd say Ian and Trevor have a good chance of being right but it's not much different from what some posters have been sharing on here for a while.
