They have been un-Apple like for a while.This product seems so un-Apple and like Tim Cook rushed it to market before he retires.
Apple always waited for tech to be a reasonable (price & hardware) before unleashing. This is like if they debuted AirPods in 2012 at a price $799 and the battery lasts 1 hour.
Battery life rarely increases for a product line when there is a set of requirements. Only outlier is the AS switch. It probably doesn’t matter if they delay for another year if they got the initial idea/use case wrong.
Oh they might cancel before release though
