It would be interesting to see concrete tests. Gamers have long preferred wired keyboards and mice supposedly for latency reasons, with the only wireless models they’ll accept being proprietary 2.4Ghz RF protocols designed specifically for lowering latency (e.g. Logitech’s Lightspeed lineup).

I have a Lightspeed mouse as part of my gaming setup and it does feel very responsive, easily good enough for my needs, but I’m not a chart topping FPS player who’d be pushing these devices to their limits.
