I can see from that list, that 2020 will bring us two types of war games. The first type (these are the ones I'm personally waiting for) are games exploring new, little exploited areas and trying something new, combining different layers of strategic gameplay.
The second ones (those I'm not so much waiting for), are those which are based on well known and proven (albeit a bit rusty) mechanics.
I'm also glad that this year will bring new, interesting naval war games.
My personal top picks: Grand Tactician The Civil War, Task Force Admiral Volume 1, Civil War, Ultimate Admiral: Age of Sail. Especially first two, seems to be developed by really dedicated and passionate teams.
