In november 2000 there will be elections in new regional parliaments. Okresy will exist in the future too. Good map of new czech regions is on this website . They will probably come soon. Consequently, I believe that the Czech municipalities should be classified according to regions only, with no references to the decaying districts.
Some further changes are also possible.
As the regional names are mentioned in the constitutional law, all changes must be approved by the Parliament of the Czech Republic. It is probable that the first-round changes will be completed in April 2001. To my best knowledge, no regional CoA and flag exist so far. The flags will probably be also quartered, perhaps pure BOAs. Four Krajs are going to change their names.
