Agree that we are all somewhat in the dark and that we can only speculate. I do believe that this presentation would serve both as a view into the process and to explain exactly why it took so long to get through it. Now that we are not yet through it, it was pulled. Again, that is just my opinion and I do not expect anyone else to agree.
I don't think they are worried about future opportunities to present because they have pulled two presentations. The oncology field will not prevent important news to be presented in the future.
