I am now convinced that the end goal of a 4DS Megabit Test Chip is still to come. I asked the investor hub if the Road Map is accurate regarding the test chip which follows after the recent megabit success spiel and after two weeks have heard nothing. This isn't, or shouldn't be, a sensitive topic. Also, the language used to describe the megabit success doesn't use the word chip anywhere which is telling. These reasons coupled with the "within the array" comments makes it highly implausible that we've made a test chip. It's called PL4.
The iMac meeting must have been about which cell structure to use in the upcoming test chip. Next announcement will be more test results and inexpensive to produce the test chip by end of Q2 next year.
