Why is there no 1.69gbit/s 2-antenna ac yet ?

[hhhd1]

When to expect to see some 1.69gbit/s wireless ac on 160Mhz bandwidth instead of 867mbit/s on 80MHz bandwidth, while using only 2 antennas, instead everyone is adding antennas ?

Asking about this since most laptops have 2 antennas only.

It seems to be coming soon, but not yet. Wave 2 AC products look to be launching this fall, IIRC.
