There have been rumours that they might. No idea how on earth it would work though. iWatch is pretty tightly coupled with iOS internals.

I dont think it would take very much to get the simple stuff like notification to work. Thats all Apple's API which is open to developers. All Google may have to do is provide some kind of downloadable layer for support for more tightly coupled things(Google Now). I am assuming that Apple lets them.

At least, Android Wear could do the same that Pebble does, isn't?
