I'm sure I missed lot of things here so feel free to chime in and I'll make an edit. For certain, medical, diseases, and overall softskills most certainly aren't finished. Hard to remember everything, but it looks like they're pretty close to finishing based on what was promised and what was taken out. As far as new features, I can't comment on that. Light machine guns, explosive weapons (RPG, LAW, etc), Dart Guns, Taser (Shock Pistol), and more vehicles (Bus, V3S, Moped, etc) are coming somehwere down the line.
Are there any new plans?
Will we get everything above?
Will DayZ be complete by the end of 2020?
