Google Health and Purchases at press day?

We know that Google Health is very likely to be launched today during the annual press day, but what else could they have up their sleeve?

Dirson.com reports that tests are being made on purchases.google.com this morning -- the service that some think will store user credit card and financial institution information to make online purchasing a better experience for users.  This may signify that Google Purchases is looking to make an appearance at press day also.

Today should be interesting!
