As of right now we expect to hear on the finalization (validation?) of the 8th and final component of the Optical Interposer, scheduled for completion by end 2019. Then we expect to hear of Tranche 2 from the mysterious DL Buyer, scheduled to close be Dec 31, 2019.
Then we can logically expect the flow of events to lead to Tranche 3 to close by end May, 2019, and a customer-validated OI by June 30, 2019.
While like others I would love a good solid update or announcement before the Xmas break, I dont expect anything until January when the DL funds are in the bank. That said, I am keeping my fingers crossed that if the 8th component can be announced before Xmas, we might pick up steam in the early New Year.
