Yahoo! is testing the Bing engine as we speak. A certain percentage of Yahoo! searches are being shown Bing results in preparation for the switchover to Bing powering ALL Yahoo! organic results supposedly in the September/October timeframe. Danny Sullivan an crew wrote about it over at SearchEngineLand.com a week or two ago. And I've seen an email that went out a couple of weeks ago to all Corporate customers of Yahoo! saying testing was going well, and the switchover was scheduled for September/October of this year.
