Do you have any references to the claims about GAE offering sql databases support? Is it something that you predict or is it something they made a commitment to?
Note that this is a page about GAE for business, so I wouldn't be surprised if SQL databases require a billable account similar to the Blobstore - don't think anything has been explicitly stated one way or another as yet though.
See under the section "Enterprise Features".
