BMW has normally had end of production in June.
No cars are made in August because of summer holidays and preparing the production line for the next years model.
September is start of "next" year model, this has been the case for over 30 years.
Hence the 6/22 EOP would mean the 2022 will be the last i3.

BMW have in some cases deviated from the above mentioned "norm" though.

My i3s was ordered in September 2020, manufactured in October and I took delivery in November.
Normally, this would have been an MY2021, but BMW did not change their i3 production before later in the year, my car is still an MY2020, verified by the VIN numbers 10th character being an "L", MY2021 has an "M".

When the MY2021 was released, several colors was NLA and some new ones were introduced. i.e my Melbourne red is no longer available and a new "gold" color was introduced, reminds me of the old Phoenix Yellow you got on the E46's.
