I'm not in a position to make any promises about future policy decisions. So I'm not not comfortable trying to speculate about future plans. I can say that I believe in the character of the current leadership, but beyond that...

As to whether it is done currently? The simple answer is I don't know. I haven't heard anything that would make me think it is, but I don't work close enough to those areas that I necessarily would.

I would be surprised if the things you list are combined in an meaningful way (obviously, if you use analytics, there is a link between your account and your analytics data, the same way there is if you use docs or picasa - but I'm pretty sure that's not what you're asking about :-) )
