I don't think google will ever try to make an OS. They will never penetrate the OS market. Competetion from old timers like Windows,Unix and free OSes like Linux,_BSD would be too much to handle. I think the direction they would be taking is to provide services via web paid by subscription. Corporations would love that idea as new technologies will be implemented on existing systems with less cost.Company to watch out for OS is Apple since they have plans to comt to the x86 architecture. Lets see how that goes (btw Apple Mac OSX is a variant of BSD Unix)
