He would have known before accepting an opportunity to speak if he was able to speak. I have a feeling this is in regaurd to recent developments and partnerships, regarding 2-6. What if he was planning to reveal a prototype, it's capabilities, and how they could bring it to market though the 2-6 acquisition of EPIWORKS and ANAD.

All speculation but perhaps? Defiantly something that should be explained in the 16th of February as to why it was cancelled.
