Availability of Fenix 8 Features

And which specific possibilities do you have in mind? Because I get the impression that you yourself don't know what's new in F8

I’am mainly interested in the strength coach. But the Hardware brings only disadvantages for me so i will definitely not buy one

Possibly the round trip routing, but doubtful you'll get the strength coaching and UI changes as these are the standout differentiators of the new model.

Not OP but I'd like to try out the strength training program.

According to DC Rainmaker the answer is zero Fenix 8 features are coming to the 7 etc

I'm just waiting for availability of 7pro features to reach the 7pro (i.e. bug fixes)

I would really like the notification center. 

By now even if you have the notification timeout set to max, it does not include all notification (storm alert, time to sunset and all these little notifications - you have like 5 seconds to look at yout watch - if you are doing something and cant look right away you will never know what the notification was, its gonw forever) and also during an activity most of the time another notification (heart rate low/high or upcoming turn etc) will replace the notification before timeout.

I don´t want new features, I just want working device with battery life as in specs. If F8 solar has same GNSS chip, I want better power consumption for F7Pro too :-).
