I would compare the track records of Civ VI and Beyond Earth. BE had one DLC and one expansion, with nothing further. No balance patches, nothing. Whatever plans they had at launch, they were dramatically cut back based on the performance in the market.
Civ6, on the other hand, was planned to have frequent DLC when it launched in 2016. They may have even planned for the expansions -- at launch -- but I doubt that they knew they would release the New Frontier Pass or Leader Pass, back in 2016. Plans change...
