Will Google ever take back control of the android OS? And who will be the best candidate for the android handset?

I think android is one of the best mobile OS but lets face it with the variations of android handsets there are bound to be too many bugs to fix. My main problem is you can't always have the best android OS version because Google is not in control of its own mobile OS. That's why I think Google should only have one manufacturer of android and it should be one of the three: HTC, Motorola, or Sony ? Please provide input I'm new to this
