Was the 2020 movie confirmed as a Kenobi movie??
Not by anybody other than the press I’m afraid. I would imagine that once we get an announcement that episode IX has begun filming we’ll hear something official about whatever the next movie is going to be. So far they seem to be keeping us informed in “detail” about only the next two movies in their release plans.
Given that they’ve announced plans for a new trilogy and a new series of films over the past couple of months it wouldn’t surprise me if 2020 was a quiet year for new Star Wars movies. With the new animated series and at least one live-action series coming before or during 2020 maybe they’ll want to avoid over-saturating the market and just focus on those properties and begin releasing the new set of movies from 2021/22?
Personally, I’d like to see a Kenobi movie finish off this duo of trilogies. If they do that, we’ll have had three Skywalker saga movies and three prequels featuring characters and locations from the OT. That seems very nostalgically balanced in a mathsy sort of way to me! After that perhaps they can move away from the time period the current movies (and animated series) are tethered to and expand the universe a bit.
tl;dr NO.
