New sat imagery isn't exactly new, Yahoo recently added hi-res imagery for an area near here, and the imagery must be at least a couple of years old as it doesn't show road works that took 18-24 months to complete.

So even though it's new it's well out of date, maybe they got it cheap because it was out of date?
