There was no gameplay or window whatsoever.Sounds like a highly ambitious title. Wouldn't surprise me if this is next gen or coming late 2020.
Expect a gameplay reveal at E3 2020 1 year from today, and then expect the release date to be 2021, the year after. .. with potential to be late in the year and even delayed into 2022.
It is definitely not next year with a showing like this. It will go through one or two E3s with gameplay showcases before launch.
