“added at some point”
Are you serious? 
Adding helicopters down the line was a given anyway since we had those in previous versions. That in itself is not much of a commitment, unless you think regression is a good thing.
It was somewhat insinuated that helicopters would not be far away post-launch. But then they low-key broke the news it would not be before 2022 and the public saw what a bug fest the new sim was in the immediate period after release, which Alpha testers knew but were under NDA.
Marketing “there will be helicopters” is of course a lot easier than “there will be helicopters, but it’s not a priority”. Seeing how many issues there are with the core sim that’s a good thing, but don’t try to sugarcoat this.
A non-free helicopter DLC is questionable unless the flight model is so revolutionary that it needed extra funding and development time.
Yet, we already have a helicopter available for free. Not without issues mind you, but it’s not impossible and I am willing to see if Asobo will offer a competitive flight model for rotorcraft that improves upon the broken mechanics of FSX.
Let’s wait and see.
