Maybe, but I'd be surprised if Google didn't port their apps over to this imaginary platform. My larger point is that now that a rich UI is becoming a commodity, non-software/platform factors will become increasingly important e.g. manufacturing, distribution, etc.
Google is releasing iOS apps because they make money from traffic. Android has served its purpose -- preventing Google from getting frozen out of mobile computing traffic. Chrome is the future brand for Google in the human software world.
while google loves android, they live off traffic, if it comes from android, ios, windows, etc they don't care they built google apps for all those platforms
