So when the soda companies released the "throwbacks" and "heritage" label drinks before, they were test running them to see if the masses would respond well to soda made with REAL sugar. So many products are dumping High Fructose Corn Syrup and starting to use real sugar again that the soda companies are losing sales because they still are using the artificial sweetener. I'm guessing they brought the real sugar soda back because a large enough niche was created during the first release.
Keep buying the real stuff folks! Down with HFCS! It's terrible!
