Are you sure about that? Only the gpu end need to have the new connector. I am sure on the hmd side it can be adapted to other inputs on thr headset end.
After all wouldn"t be silly to have a connector with only a future use only.
How long will it take for some benchmarks to appear online?
Hard to say. But likely for sure around the 20th. Lol
Generally speaking, ndas for this type of thing lift about a week before release.
As far as I'm aware, no journalists have samples yet.
