Great question — answering as the UphillTech team:
Writing for season 2 started on January 2018. * Filming for season 2 ended on November 2018. * After that, they went into post-production and it was completed in April this year. The trailer with the date announcement was released on April 26, 2019 — 33 years to the day after the day the Chernobyl disaster occurred. You guys already figured out the connection of the season 1 release date on Michael's suicide. At this point, we can't turn a blind eye to what's going on with their clever game here. It is not a coincidence, they are purposefully doing this. In order to achieve this, they either have to plan this ahead and fix their production/post-production dates and go according to the plan...
