Sure, lots of suppliers claim to have access, but if you press the story is that they will try to get the chip if you prepay for 10K units using wire transfer.  Tread carefully, ali does not have protection like aliexpress.

I have a quantity of s9 that were purchased around $1385 and $1425 USD.  I could disassemble them and get several thousand chips at roughly $7/unit. But that's not a good deal, of course. 

Let's see if anything pans out.  Has anyone RE'd the s9 to the point that the comms format is known?
