Why is there still no announcer for Grifball?

I was very confused to why 343 still hasnt managed to have the best multiplayer voice actor: Jeff Steitzer, come back and literally say 2 things: “Grifball” and “Assualt” before the beginning of a match. 343i really knows how to slack because I don’t understand what the big deal is to not have a announcer for one of the greatest gamemodes out there. When you first start a game of Grif or Assualt it is just the music. I really wanna hear Grifball and Assualt because it is a tradition in Halo series to hear the announcer and have him announce the gamemode before the game has started. I hope they at least have the announcer say Infection because that gamemode is gonna be awesome. If anyone knows why 343 is holding off so long please tell me.
Thanks,

My guess is it has to do with it all being just one game mode rather than two separate game modes.

I swear I heard the announcer say ‘Grifball’ when I started a match. Maybe I was hearing things.
