Yeah, when you preorder games digitally on Xbox One you download the entire game to your hard drive but you have to wait until launch date to play it. The game's size being updated to 20.26GB is basic confirmation that Ubisoft has completed the finished build of JD2020, has posted the full game on the Microsoft Store ready for you to download now, and it's just sitting there and waiting till launch date to be playable.

The 100mb that was there before was probably for development testing.
