Disclaimer is that I've known Meagan and Eric for a very long time, almost a decade before they even started skating together. Haven't talked to them since this has made it's way through Twitter and here in the last 2 days, but just some additional thoughts based on the back and forth and variety of different assumptions now being thrown out:
I think Eric and Vanessa were considering skating together for a while, and once Vanessa found out that her release from France was going to be quick and have no issues (this is also 100% confirmed), I believe they immediately wanted to go full-force. Understandable since if they are trying to get to the Olympics again, they only have less than 10 months to get everything together. If I had to read between the lines, I would say Meagan's posts are coming from a place of being somewhat blindsided by the quick moving forward once the release happened. Obviously 'Duhamel/Radford' are accomplished as a team and like I mentioned before, CV took a lot of typical opportunities away that made everyone scramble, and I would think Meagan was waiting it out while Eric had his own unknown plans.
Eric and Vanessa had been practicing at the same rink Matte/Ferland in the weeks leading up to the World Team Trophy, and I have also heard that this was a buzz around the skaters at the event last week. As I mentioned in a previous post, pretty much all of skating Canada knows this by now. I know people are rambling on with 'we don't even know if it's true', most likely because Dave Lease was the one to hint at it, but it is known widely around the rinks, so to speak. I believe they also don't have an official coaching team yet, and they aren't working with Bruno.
I have to admit that I don't read a lot of skating articles because I think most of it is stuff that is already known or the same thoughts repeated in a different way, but I can't remember Duhamel ever being vocal about wanting to step away from skating. I could be wrong, but I think it was more moving into pro skating and starting a family. I remember when she was back on the ice post-baby, she was trying to land all her triples very quickly and we saw how ambitious she was in such a short time during Battle of the Blades. She's not someone that was ever ready to hang up her skates AFAIK, but I did always get the impression that Eric was done and had so many other things he wanted to focus on.
