That is definitely not the case locally on a tile basis in most 
situations but it is of course possible that Microsoft manages image 
data and metadata on a larger scale where multiple images are dealt 
with in sets and not individually.

Just to make this clear: My mail was not in any way a complaint that the 
images are too old.  IMO for OSM extending high resolution coverage 
would often be more important than updating images - after all high 
interest areas are usually also covered in other sources than Bing and 
it is not that costly to supplement older high resolution images with 
newer low resolution images to be able to see where things have
