Most Realistic Announcement for 3/12 inside xbox?

I'm thinking it could possibly be:

- PC/Switch port

- Reach for mcc

- ODST firefight

- Customization update

IF WE ARE IN FOR SOMETHING CRAZY

- Halo 3 anniversary????

- Reach anniversary?

- infinite beta

- all of the above

- none of the above

Im thinking (as a non PC owner) we'll get a PC port, which wouldn't be too exciting for me but id be pretty happy for yall especially if we get crossplay lol

Id be pretty psyched for reach since the original game's population is slowly dwindling and its my favorite Halo so dap. Hey, maybe this speculation was on to something? https://www.onmsft.com/news/halo-mcc-gets-major-update-with-xbox-one-x-enhancements-team-is-looking-at-halo-reach-port
