This isn't intended to be a negative post by any means. I am trying to point out that I recall updates that had more features added than this one had less of a download requirement.
9gb is a hefty amount of data to download for what people say on here (Not intended to be a big of an update/monthly updates/don't get your hopes up/been discussed bla bla bla).
Heck, I think I remember our anniversary update was probably 9 gigs or so for size.
(Just looked it up via google and old release notes. PROOF - Anniversary update was 8.90 GB for Windows 10)
What I see in the patch notes in terms of additions to the game, I don't think its really tied to what we got.
