All of the soda companies are doing this. The use of corn products in E85 (fuel) has caused the demand (and therefore the price) for corn to go up, and because the government is subsidizing it, the farmers make more money selling corn for fuel than for food. This makes products like corn syrup more expensive, so cane sugar is the more economical choice. I think this "throwback" campaign by the soda companies is just a marketing gimmick; I don't notice a difference in flavor, but that's just me. Others may feel different.
