My best guess for the start of human testing is also 2015. (Early in 2015, for me.) I too would love to be proven wrong but so far NNVC has never surprised us by being early.
I note that Dr. Seymour loves to say human clinical trials will only take a few weeks, and he can whip up a new 'cide in 2 weeks. The former estimate ignores the many months (or years) of preparation before NNVC can even start the human trials, and the months of review afterwards by the FDA. The latter estimate is for the first crude version of the 'cide to test on rats, and ignores the years of tweaking before there is a drug to submit to human testing. In other words, they are estimates that are meaningless in the overall scheme of things.
