Does anyone know or have heard anything about the new gyroscopes & accelerometer having benefits for weightlifting/ strength training?

That is not needed since the current gyroscopes & accelerometer will measure weight training movements in all planes. The new ones can just handle a higher G-forces before "bottoming" out. There might be some benefits for impact sports like tennis or boxing. What you are asking for would require extensive algorithms sensing specific movements.

Honestly, weight training is very difficult to track and there is a huge variation not only because of the number of different movements and exercises but also because calories consumption is greatly affected by muscle mass and the resistance of the weight. It’s probably the least accurate of the workout options.

Marzel, just curiosity, in terms of the accuracy would you say the watch would likely under estimate the calories burn during a strength training workout or over estimate?

Not Marzel but it is a crapshoot either way. Weigh training is an anaerobic workout and there is NO way to measure caloric burn with ANY accuracy. HR is basically irrelevant in anaerobic workouts and not useful in calculating caloric burn. So it would be a pure guesstimate and you would have NO WAY to know if it was over, under or about correct.

Almost always overestimate. Having said that, Fitbit is clearly worse. The issue with most tracking devices is that they assume constant weight lifting (almost no breaks). Apple Watch does compensate somehow using the heart monitor to detect rest and it appears to have better algorithms but still if you compare it with what we generally know about calories burned during workouts it’s a lot.

The Apple Watch on average gives about 300-350 calories per hour during strength training for an average sized man. In reality, from what we know even Tabata and CrossFit don’t reach those levels.

Completely agree.

Edit: Btw another issue with weight training is that energy keeps being consumed even hours after the workout due to muscle recovery so in the end although the watch overestimates calorie consumption during the workout might underestimate the overall consumption after 24 h. It’s really complicated actually.
