in the leaked documents of the nexus tablet and/or jelly bean, it was said that google will directly update the tablet through new features in jelly bean. Google, not asus, will be updating its tablet. Something very different from google's phones.
I was speculating that google might implement this with phones that it sells directly and made the poll as a "what if." I think this is very possible and not a pipe dream. You have to imagine google isn't happy with the way carriers roll out updates and fragmentation issues.
