Are newer features coming to Fenix 6?

Hello,

I'm a F6 user and I'm interested in some of the new features recently published, but absent in F6.

As Chris replies in Fitness Age 2.0 thread:

"When a new feature is just introduced in a new product in the Fitness segment, such as the Fitness Age 2.0 that is seen in the new Forerunner 945/LTE models and interest is shown in it arriving in the Fenix series, we are happy to pass it along to our engineers for consideration."

Is there a chance it comes to Fenix 6 as well? How about HIIT, eBike and other profiles? Any chance they're introduced as software update for Fenix 6 when Fenix 7 is released?

How did Garmin treat the watches historically?
