https://www.reddit.com/r/GarminFenix/comments/1hwly08/fenix_7_pro_vs_fenix_8_novice_question/ The release dates of the Fenix 7 Pro and Fenix 8 are 15 months apart. As others pointed out the Fenix 8 is the first model developed on a new codebase. That means that development on the Fenix 8 is considered future proof (as it can be re-used for the Fenix 9/10/etc) and development on the Fenix 7 has limited value. It is therefore likely and in Garmin’s best interest to minimize the development time spent on the Fenix 7. (they will typically do just enough to retain customer loyalty).
