Thomas Bindl has found another new Google layout and blogged about it.  Basically this version replaces the indented second listing with an indented list of multiple subpages (url only, no snippets). 

I am not a fan of this as I think the snippets that go along with the urls in the serps are very useful to searchers trying to figure out if the page is what they want or not.  It sure would be nice if Google would post a a nice explanation on all of these different layouts and let us know when they have finalized these changes HINT HINT.
