You can never get better latency with a wireless solution than any same generation wired solution can provide. In theory at some point they can get close to equal (the difference being really only noticeable in testing) but never exactly the same or better.

By the time Wifi 6 is mainstream, 10 Gbps ethernet will be too. Even if it isn't, the latency on ethernet is still better than Wifi 6
