One clue: if there is no cascade of PRs coming out from the company starting this week, then it is the silence before the big tornado, big news will drop very soon.
Next two big milestones for NWBO are combo patent and facility certification. The deal may or may not wait for these two milestones.
The most important thing for NWBO is that the science is validated and NWBO is for real, now the huge potential is there and for real, everything else after that is trivial and matter of execution which the BP also can do it and do it better.
With such a golden business opportunity, why BP want to wait or hesitate to act on it?
