Additional Modes and Maps

[sam]

I could see myself liking this game a lot, especially the AI skirmish mode, but I need to know how much is going to be in this game.

At launch, how many modes or maps will the game launch with? Will there be addition modes like domination/area control like in Halo Wars 2 blitz, or horde wave survival? Or will it just be the standard PVP and vs AI destruction mode?

Also, how many different map will there be on launch?

It definitely seems like the devs are focusing on adding content through new units and skins, but if the only way players can use that content is in one mode on just a few maps it's not going to last.
