Yahoo Offers Updated Imagery for Maps/API

Lots of coverage of the new additions - but no talk about the sources. If you have time Silicon Beat has the best coverage inlcuding the question: "What took so long" and the good natured competition between the big wigs at SDForum. The "official statement" offers this description - my questions in parens:

Comprehensive Nationwide Satellite Imagery Coverage
Wall-to-wall coverage within the lower 48 states in the US. We are going for the best coverage nationwide, from the streets of New York to every inch of Redding, CA. (Details of cvoerage are where? What's the resolution? Who took it?)

Global Satellite Imagery
The product features global images at 15 meters per pixel (zoom level 5, medium resolution), which basically lets you find and see every city, town, and major land feature in the world at medium resolution.

Global Maps
We’re releasing maps and overlays at medium resolution for the whole world as well. This should help you view not only the suburbs of Bangkok, Thailand, but also help see the context of the imagery in hybrid mode. (Sources?)

Update 4/13: One source claims imagery is from GeoEye. I've not confirmed that. I've found imagery from i-cubed and Aerials Express in my travels on Yahoo Maps.

I reviewed the new Yahoo Maps beta and, as typical, I typed in my address...a relatively new street (2 years old). For starters, I used the old Yahoo Maps and, much to my surprise, it geocodes the address and displays the street correctly. On most every other mapping portal, my street is missing. However, the new Yahoo Maps beta version is not using the same database as my street is missing entirely. My address will geocode to a close approximation but I found it strange that the street is missing in the displayed map. Why the two different databases?
