I also know that something like this should probably go into the weekly “Feature Requests”...

I don't think this is possible at the moment, but it certainly sounds like a feature that would be useful for a lot of people. It might be worth putting it as a request in the Xbox Insiders weekly feature request thread, it's the ideal place to make new
suggestions: https://www.reddit.com/r/xboxinsiders/

That is a feature that I never used but many have requested that feature or something like it be returned. I am sure there are posts
HERE that are requesting it so you might consider going and searching for and voting for the feature.

That is pretty cool, but I think it was thrown around a little too loosely, it will probably be (not that I know) like 5 different faces, some hair styles, and clothes. Not anything like sport games where you get to customize their size, body structure and
facial features (like size, placement and color). But it will be something cool and different. I also like the whole momentum going with mantling walls/objects.

They need to start releasing videos like this on a weekly basis. It would be nice to go more in depth with some of the features.

Oh I'd also like to ad, the last year of weekly sets has not had a single preorder request in any set. I've done almost all of them or have come close and not seen a preorder for completion on a weekly set
