Tbqh, it's the problem for Garmin itself - they want to sell new Fenix every year but the old one is already very good so they are segmenting their own product by holding off updates on the old watches for now but it's only going to work for so long until there is either nothing to update or they push down their value under that of competition's. E.g. Google could give Garmin a scare of its life if they made a watch with a MIP display, ANT+ support and power profile to run GPS for 8-10 hours - I'd buy such a watch from Google instead of Garmin just because Google is going to support it for longer (not that Google is known for longevity of its support but it's still better than Garmin's).
