I have always believed and still believe that PTK will get bought out sooner than later. In my opinion, once agreements are in place (and NRE revenue is announced) an offer will come.
.......that said, whose to say that PTK can't split itself into more than one entity and spin-off current technology while retaining the rights for the use of other works-in-progress for future gains?
Just saying that wouldn't be such a bad idea.
