I’m not so sure we will.
While you may experience some bumps and bugs during this beta period, it does mark the official start of Halo Infinite Season 1, with all day-one maps and modes enabled as well as the full Season 1 Battle Pass.
All day-one maps and modes enabled already.
So what we have now will be what we have on Dec 8th (day-one).
We might have to wait a while before we get anything else.
