The January 2008 Yahoo Search Update is reportedly now fizzling out. A WebmasterWorld thread says the results are beginning to look stable and the update seems to be settling out.
Typically with Yahoo updates, the results initially look out of place and some listings seem a bit awkward. Towards the end of the update, results stop moving around and results begin to set in their place.

As of yesterday things seemed to have settled down. It looks like we might be at steady state now.
