The end of paravirt_ops?

I belive the time frame for dropping paravirt_ops is many years, so it would seem premature to start worrying just yet. But the overall direction seems to be that more and more hardware gets good virtualization support - it seems likely that in a few years, a regular cell phone will be using virualization to allow non-trusted applications to run with decent security, much the same way the PS3 does today. At such a time, I think it's likely that paravirt_ops will not be missed by many.
