Anonymous 4chan user on /vg/ posted what is supposedly a picture of the main menu of a halo infinite “flight” or beta test.
and appears to be answering questions to an extent
It shows them in “Delta Group” and has a username which does indeed match up with 343 developer names.
soon after, twitter user surasia4 posts their own screenshot too, not sure if they know eachother
will update this post if more come out. barn leak anyone?
