Exactly, there is no deadline, and that means that the news could be tomorrow or in 3 months, or more.
I am working under the assumption from my conversations with CC today that it would be typical that Dr. SV will make some sort of formal announcement regarding his vision for the company first, before milestones or partnerships will be released. We really don't know much about where he intends to take the company other than the remarks he made when accepting the position:
Dr. Venkatesan commented: "I see immense market potential for POET Technology's III-V complementary semiconductor fabrication process. The industry is at inflection point where new innovative solutions are needed. Integrating electronics and optical devices on the same chip monolithically can revolutionize many segments of the semiconductor market. I am excited to be part of the team."
This is hardly an all encompassing statement of his vision for the company.
After he makes his first speech on behalf of the company, then news can be released.
And to my knowledge, no one, outside the BoD, knows when that will be.
