I think... if it is true that final patches was result of a lot of overtime, it is an extremely serious and horrible problem. It shows that even if FDev will work harder, we can't receive proper updates any more. So I wish it is not true.
I have been working from home for 2 years and have noticed that my daily working hours are much longer than when I am in the office. However, significantly more time is required for meetings and documentation. The workload has increased with the same work results.
