Oreo has been out now for several weeks, and Samsung is already developing the new update for the Galaxy S8 and S8+. This is great news as Samsung has been notorious for updating devices super late. So far Samsung has not mentioned when these updates will begin rolling out to devices. Hopefully they will open up the beta program so we can run beta builds of the Oreo update leading up to the official roll out. Samsung has used multi-CSC firmwares which means they should be able to get the update rolled out quickly once it is ready to go.
