The irony is that Panama had a very similar feature when it launched, using a slider to show increased traffic levels tied to bid price. Now Panama is going away with the Yahoo-Microsoft deal.
Bid Simulator should prove to both be popular and incrementally boost search revenues for Google.
Postscript: This is now official, and the Google AdWords blog just announced it a few days later.
