Probably not. I think Apple has decided to prefect the HR monitor in Ver 1 and add additional sensors as the technologies progresses.

Just getting optical HR monitoring to work will be a big plus. However having multiple sensors that only half work will be seen as a fail.
 
Agree with Julien. The HR monitoring side of the Surge and Charge HR leave a LOT to be desired. Hopefully Apple will be able to implement something more efficient than what Fitbit has done. According to both the Surge and Charge I'm the fittest man alive. I can finish a complete weight circuit and a 45 min cardio session and never have my HR go above 89 🙂

I'd love to see a pulse Ox meter as well, but I'll settle for workable and accurate HR data.
