Now that Yahoo and Microsoft are beginning to migrate Yahoo advertiser to adCenter, there are some concerns that the prices of a click will increase when all is set and done.
A WebmasterWorld thread points to a press release where GroupM Search said advertisers should see a 78% increase in cost-per-click prices. Why? "Increase competition."
My big question is, are the CPC prices on Google 78% higher than those on Yahoo or Microsoft?
Do you think prices will increase that much? Take my poll:

If you are just advertising on Bing, then yes Costs Per Click are going up as soon as Yahoo Sponsored Search switches to Bing. But if you are already advertising on both, it will likely all equal out in the end - you've already been paying higher costs per click on Yahoo the whole time, they are just moved over to Bing now.
