@manuel-silvestri The S9B development has not yet stopped. I think Suunto is a nimble forward thinking and moving company. They want to make sustainable products. I agree that new hardware could have some improvements on the S9baro but I doubt something major. The question to ask yourself is what kind of watch do you need? For me, that is simple, long battery life, durable and reliable. The S9b is perfect for that. What I want in the S9b that it does not have, training plans, was there when Movescount was working and I hope will come back with syncing to 3rd party software.
There is little I could ask for hardware wise that I need. I would love to have the map implementation on the S9 that is on the S7. That will not happen for a long time as it will required either development of mapping for an S9 successor or development of an S7 successor with S9 battery life. Neither of those AFAIK would be on the horizon in the next year or so.
The S9b is now a helluva watch; the navigation improvements with Komoot turn by turn, waypoints and POIs are awesome. Couple that with the best navigation tools of any manufacturer, which SA has, and you have an outdoor watch winner! I am hoping for offline loading of maps in SA and gradient shading, that would make my day!
