I really hate to be that annoying naysayer, but those initial phases where practically only safety is tested mean nothing, lets be realistic.
honestly I think their concept only works to a minor extent (small amount of weak new hair that will die out as quickly as it was created), and thats why its still not marketed after all this time. if they need a decade to find some miraculous "special compounds" to make it worthwile, whats the strength of the "but wounding is proven to work" argument in the first place?
if I had to bet, I d say they ll keep delaying for 2-3 years and then just dissapear. what shiseido/replicel are doing looks much more plausible and potent to me.
