From what I can see, the 4th edition conversion of WotBS started in October 2009. After that point, Wizards revised it's core design of monsters with the publication of Monster Manual 3 in June, 2010, and then you saw some major revisions of the 'core' monsters with Monster Vault, released recently.
Now I figure that all the encounters in WotBS have been actually tested for balance/fun factor already but, the length of combat and general flow of it did change some with the new monsters. My question is two fold.
1. Have the change in monster/encounter philosophy come into place in most published 4e editions of WotBS?
2. Are there any plans to go back and revise the old encounters to fit the new model?
