I wonder if they're planning to use Tagatose. I've heard some claims that certain Soft Drink manufacturers [Pepsi - they alreayd have a Diet Pepsi Slurpee with Tagatose and Splenda] were considering a reduced Calorie canned drink made with it and artificial sweeteners. Perhaps Coke beat them to it. If it is truly half the Calories, it would likely be pure Tagatose...as Tagatose has just under half the Calories of regular sugar. If they started offering something like that [a Diet Cola made with Tagatose] in restaurants I'd get it once in a while. Tagatose doesn't seem to cause me any trouble weight-loss wise, and because it is 0 GI, I don't count it as a net carb.
