Apple is not going to give us the moon in 1st gen, or even 2nd gen, even though they could, they won't, unless someone else could catch up to AW in both HW/SW. They own 70% smart watch market, no need to hurry.
They will make gradual change each generation, ensure profit are maximize by not putting in latest HW design chip, since it tent to be most expensive in cost to Apple.
Come back in 3/4 gen, or until someone else could get their act together to really come up with something legally could take away some smart watch market from Apple.
Until then, change will be on foot speed. Remember, techie like us are minority, I know lots of people are perfectly happy with iPhone and AW, even though they only use a very small percentage of capability and very few 3rd party app.
Grandma and grandpa and 8 years old does not need or use all the apps.
