Possibly, but it's in the right neighborhood. It depends on whether we're counting from the time of design/initial fabrication or actual mass production and general sale.
The point is that 12.5Gb/s SerDes pretty much means they'd be practically to 10/40G. At least in the DC networking world this puts it several generations back.
NPUs are not used in data centers. They don't need the expensive but totally flexible network processing capabilities. Think carrier and enterprise access networks that have lower Ethernet bandwidth requirements, but higher processing requirements per packet.
