Which regiments are upcoming in-game?

This may be posted somewhere already but I searched and didn't find anything.

1) Do we have any insight to which regiments are upcoming 'soon' in-game or is that not known by anyone but the developers?

2) Are all regiments listed in Company Tool going to be active regiments in-game at some point in time?

All units listed in the tool are projected to be available in game.

Thanks! I thought maybe there was a timeline as well for upcoming regiments to be included in game but there likely isn't as devs probably want to keep that under wraps until the patches release.
