That's fair, but I think having a game explore near future equipment and tactics is also interesting. Personally, I prefer the hypothetical entries in the franchise like SF, BS and technically CW over the historically accurate titles, but I also understand liking the historical titles. Ideally, we can have both.
I see what you mean, but like you said, BFC is stubborn, they didn't switch up Shock Force when the Syrian Civil War broke out, I doubt they are willing to totally revamp Black Sea.
I think how long we will have to wait for a game based historically on the current war depends on how long the war will go on for. BFC have made it clear they are not comfortable with profiting off an ongoing conflict, so it seems like the war will have to end before BFC will consider making a game about it. They can reuse many of the assets though, so development time would probably be reduced.
