Original production timetable was January-June (6 months), for release June 2021 (12 months later). They got about 2 months of shooting done before the shutdown, so they have maybe around 4 months left. But with added safety measures and crew limitations, I expect that to go longer. If production starts back up in September, we're looking at them wrapping around December-January. Maybe even February. Whereas before they had almost a year of post-production, under this new schedule they'd have maybe 8-9 months to complete the film to meet that October release. Even if we assume Reeves has been doing some post-production work on the material they shot during the shutdown, that's still a pretty tight window.
A delayed release wouldn't surprise me, but at this point I just want production to start up again.
