The way I see it is, realistically, these are Dr's not business men. They go to work every day with one goal in mind. Developing quality drugs and advancing the current pipeline. They have enough cash to operate through 2014. They simply do not care what the pps is nor should they. They are consumed with the science not the dollars and if the science succeeds the $ will follow.
They still need to "sell" the idea... the patent office is filled with better mouse traps that never made it to market because they could not "sell" the comcept to the investors to get the production and marketing up and running. GIVE ME A T.... A..... B.... you gotta sell it
