Totally Q3 2020 beta release! Last I checked while watching SaltEMike he stated that only 40% of total art had been completed. So there's that, the missions, the A.I, the flight model, optimisations, core tech, network rework, the remaining ships, Vulkan integration, etc.
I mean, they'll totally make it! It's not like Covid-19 will do any harm to them financially.
