Lewrock, I have continued to be in the camp that the PDK's completions are the final step to unlock the mass commercialization, the Tier 1's have been testing LWLG tech sine the first commercial proto launched in December 2018, so when the PDK's are readied it is not a question of whether customers will want to incorporate them, that has long since been determined (under NDA agreement as yet), my early estimation on PDK development was in the range of 6 months, which since first spoken of in May 2021 is about now, so I think we are in the ballpark timing wise as to when these PDK's could be announced as ready to go to market soon, jmo
