As a developer who actually works in industry and know how WFH just can demolish the production timeline, I would say, WFH timelines =/= Actual production timeline in office. Because most, if not all companies are facing productivity issue in WFH situation where work efficiency has reduced to a crazy 40% less for game development.
Unless everything normalize and everyone returns to office and work in office environment, this kindda situation is unavoidable and incalculable.
That's the reason we are witnessing so many delays from 2020 for many games. So be considerate about that.
