Since I can neither prove nor disprove tape out, I cannot make a call on it.
Let's look at what they have said.
The initial process is what is called a bullet run, it will allow us to get a finished set of wafers in approximately 24 days from the date we tape out.
Current chip production has an expected delivery date in early/first half of December.
24 days + a few days for packaging, resulting in early December delivery. Sounds like they might have actually taped-out. In November. 3 months late!
