You can get throwback Pepsi here in the States as well as throwback Mt. Dew and Dr. Pepper. I think there was a run of throwback 7-Up as well. As the price of corn continues to rise to meet our federally mandated ethanol demands, I predict we'll see a return to the use of cane sugar as a sweetener. It's already happening with many products advertising "no HFCS" on their labels.
I think you’re right but it will probably happen in Canada first because of the protectionism for US sugar growers; the price of sugar in the USA is ~4x what we pay here, which is why most American soda producers switched to corn syrup in the first place.
