More game types soon???

I’ve been playing Halo since CE. I love everything about the franchise and will continue to support 343 through their baby steps of Halo. They really did it with Halo 5, they revived the franchise. One complaint that some friends and I all have is the lack of game types. We are all used to a dozen great playlists to run through in the previous Halo games. I was wonder what you guys think and if some of you know anything about when they will release more game types?
