This guy talks about "reinvigorating the cola industry" as if such a huge market needed reinvigoration. There's only so many people you can flog cola to...the market isn't infinite.
Anyway, history has proven that screwing with cola just don't work. Cherry and diet have been the only modifications that ever had any staying power. The lemon-flavored stuff may stick around since people have been doing it themselves for years anyway, although it doesn't quite taste the same.
I don't foresee Pepsi Blue and Vanilla Coke lasting very long.
