Not Enough Content? (eg, Maps, Modes, Playlists, etc)

I don’t know if this is true but I heard that this multiplayer beta is going to represent the final multiplayer portion of the game when it launches on Dec 8. If that is true then the content we have right now is not acceptable for a halo game. We are missing big game modes like infection, fiesta, FFA, team doubles, SWAT, snipers, VIP plus countless more. This is pretty much repeating the halo 5 launch all over again if what everyone else is saying is true and i don’t know for how long I can play this until I got bored of this game. If what i am saying is a non-issue and all of this is wrong ill delete this post if i can.
