Lee has a screenshot, click the thumbnail to your right, of a new Google SERP layout which includes a different designated spot for the “related searches” and also includes links to category refinements.

I think it looks decent, and its about time they made some improvements to their SERPs.  That said, I can’t imagine this one will stick due to the fact it pushes the Adwords ads in the right column down removing at least one ad from above the fold.  Would you be pleased if it was yours that got knocked out?

Lee also points to some other SERP layouts that have been found.
