So, still no Android Wear 2.0. I've pretty much decided not to stick with the ZenWatch 3, given the rumors that Asus is exiting the market and with this delay giving me the willies about how Asus will support the watch going forward.
I'm trying out the Huawei Watch 2 Classic instead. It's a nice looking watch, more features for more money, not too huge, and so far I'm liking it. It's a bummer though that Asus seems to be kind of dropping the ball a bit on its watch business.
