Are Matches Really Using the Whole Map? And Are these locations already in the game?

Are these locations already in the game?

I know they are concepts, but I was wondering if they are already a thing.

I haven't had a chance to try the game yet. Hopefully I'll get into the next closed beta.

Also, today I was listening to a streamer who said that the game is nearly perfect, but there's one big problem: all matches always converge on the same point. So there's a huge map, but basically you always end up playing in the same area. Is that true?

I read that the areas you have to conquer are different in every match, right?
