From one of the comments I saw on a different site:
"I have a prediction, I think they will soon have a service like mint.com to encourage people to move all their finances over to google wallet. Why would they do that? If they know what we spend our money on they can advertise to us better, and make more money from us, we get a money managing service they get to sell our info easier"
Makes lots of sense, but for some reason, scares the heck out of me.
