It’s time to clear your cache. Yesterday we added over 50 terabytes of new imagery from DigitalGlobe to the World Imagery map. This release includes 30cm imagery for the continental United States and 60cm imagery for large parts of Western Europe.
The cool part, I agree with James Fee, is the metadata tool.
With the Identify tool in ArcMap or the ArcGIS Online Content Viewer, you can see the resolution, collection date, and source of the imagery at the location you click. The metadata applies only to the best available imagery at that location. You may need to zoom in to view the best available imagery.
This blog post sounds so much like the ones from Google, Microsoft, et al. about imagery updates.
