Regarding about new gametypes

I’m curious if 343i have plan for bringing back the old-school gametypes like Infection and Action Sack. They were a adequate form of stress relief for players who like to take a break from competitive gaming and wish to hone their other skills in power weapons I.e. shotgun in infection…Etc. It would be great if they thought about introducing them sooner rather than later like all traditional Halo games used to do!
