I'm jealous! I've been waiting forever it seems like and still don't have mine

Not much longer though.
The M has a 56.5 top tube so that is likely to be closer to a size 56 though perhaps slightly large in that and some of the other dimensions.. Mountain bikes have been going to longer top tubes and shorter stems the last couple of years. There is a lot to be said about having a slightly small frame though, especially for road but for off road use too. Anyway, I hope it's is a good fit for you.
I'm sure to be happy as long as it fits 40c tires. The geo leans a little more to the road, similar to the Diverge, with a tight rear triangle and I think I'm going to like that. Especially since I think it will see a lot of road miles either on century rides or mixed road/trail rides.
I just ordered all the remaining parts to complete the two extra sets of wheels - a pure road set and the wilderness adventure set. I've got a couple more parts to get my Garmin mounted and functioning on the new bike and then will be ready to ride. I decided to wait a bit to convert to Di2 though it will happen sooner rather than later.
It would have been nice to have ordered over the weekend as they had the 20% Performance Points offer. I'd check to see if there is a way to still get in on that.
I'll give you an update when I can. And will be anxious to hear a ride report from you too.
