Time will tell max.
another observation - copy and paste an ebay auction title into search and the results are different.
Before - the top results invariably were ebay and whatever affiliate site had copied the auctions onto their site and used the titles as their page titles.
After - specific words are pulled and official sites for those words are returned. a product named example returns example.com, not the entire exact match string.
Perhaps long tail exact match in titles carries less weight and/or a titles core subject (as determined by google) matches official sites more often. This change may be a simple title weighting tweak.
