Yes, I hope this thing finally gets legs. I was looking at getting a little more at this low price but now will have to see what is afoot. While I have been very critical of management's comfortable, well-paid, slow pace, I still think PBT434 could be a winner. Perhaps the "hot seat" for GK might be an inspiration to make things happen...at least I hope so, for all of our sakes.
