In the UK it still uses sugar, and imho tastes a whole lot better than the HFCS version.
The other year when sugar prices were near equal to corn, Pepsi and Dr. Pepper distributed soda with sugar only throughout much of the United States. I haven't followed the prices of sugar since, but I would gather the price went back up either naturally or through congressional means.
Now I looked it up, Pepsi markets "throwback" brands which use sugar.
