Bitmain's 16nm Bitcoin ASIC orders have recently been shifted from TSMC's Fab 14 in Taiwan to the fab in Nanjing, China as Fab 14 will be upgraded to support a 12nm manufacturing process. The orders are expected to begin shipments in May, the sources said.
Read that carefully folks... Order were shifted to the China fab, presumable also a 16nm one. Fab 14 was being upgraded, but Bitmains chips would not be coming from there now, they will be coming from the older tech China plant.
I fully agree. The more useful information was, that they talk about 7nm with TMSC. This technology will be more likely the base for the S11 ASIC than 12nm.
So the good news is, it seems that they didnt even start the 7nm design process.
