Google to sell Motorola to Lenovo?

Google may sell Motorola to Lenovo within days. What do you think about this? Did Google just decide Moto Wasn't worth as much as they thought? Or did they make a non bias deal with Samsung? Or, is Google transitioning to become more like Microsoft was in terms of PC software, and is getting rid of the unprofitable phone business? (Unless you're Samsung) Thoughts?
