So I haven't been able to bring myself to look at what it says, but apparently this is a huge spoiler and gives away the entire ending. In my brief quick glancing at it, someone is either dead or not dead (which says absolutely nothing tbh)
In the video at 0:17-0:18, one of the employees from 343 is flipping through a script and one ends on the last page. Watch at 1080p and at your own risk.
I've also attached the aforementioned picture in case the video gets taken down.
