Do you think Sleep Tracking will require new hardware?

The title says it all. I've never owned an Apple watch and am seriously considering buying a series 5. Now, I know no one knows what Apple will do, and that's not what I am asking. Based on your knowledge or intuition, do you think sleep tracking could come with the next watchOS ? Or do you think it will be tied to the 2020 Apple watch only?

I personnel think if sleep tracking is a Series 6 only feature, it will be artificially made so. The thing is I know technology evolves every year and I'm not interested in waiting forever. Plus, the apple watch has plenty enough features for me EXCEPT sleep tracking which my Withings Steel HR has. But I would really be pissed if next year Watch has sleep tracking as a differentiating factor whereas many other smartwatches have had it for years with great accuracy and without specific hardware (I think).

I think there will be a native app with a generation of the watch that can boast more than 18 hours battery. I know that I always even on a bad day get over 24 hours, but Apple will wait until they can say the watch has say 48 hour battery life (which really will be nearer 55-60 hours) then they will promote sleep tracking IMO.

I was kind of hoping that Apple would implement the SpO2 sensor in conjunction with Sleep tracking, as the level of oxygen in your blood during sleep is a very good health indicator. But, after looking and reading about Garmin's SpO2 sensor on their Fenix line, it appears that 24/7 data is a real battery killer for those watches. Perhaps Apple is waiting until they can actually give a decent battery life for the SpO2 sensor laden watch. In the meantime, I have my trusty stand alone device that does talk to Apple Health.

I've had sleep tracking on my Apple Watch for years. Just because there's no native apple app that does it, doesn't mean there aren't third party ones which work perfectly well.
One wonders why Apple hasn’t offered their own native app. Cynically my guess is they’re holding back and requiring new hardware to run, despite the fact it’s not necessary.

I would think yes, new hardware is required. I feel Apple is working on improving the battery life, data analysis and possible additional sensors to improve sleep tracking compared say Fitbit or others offerings. My Fitbit is good but I don’t think its too accurate. I can be staying up late, sitting in a chair and my Fitbit thinks I’m sleeping.
