So I think maybe the question then becomes (with a wide margin of assumption) of possible reasons for the TRAB to have been dissolved:
1... The direction of product design for an Apple product has been established.
2... Apple is no longer interested in POETs technology. That is a hard one to accept given what we know of the potential for POET to do many applications that Apple would want.
3...Potentially POET is formally distancing themselves from Apple for strategic reasons.
a. If POET is going to sell products to Apples competition then the association with Apple had to be ended.
b. Apple is getting too close for comfort as POET progresses towards full integration. Could they have been waiting for some proof of concept with the intent to take a run at POET once they felt that the technology was derisked? In fact if you take this one step further it is in keeping with public disclosure policy now.
