IPD isn't that, they're talking about focus. All current VR headsets are focused at a fixed distance, typically around 2 meters away though earlier headsets focused to infinity. Anything outside of the 2m distance can look incorrect and it causes visual weirdness like depth of focus blur to instead look uncannily sharp.
Not fixable without varifocal lenses which adjust focus depending on what your eyes are looking at.
No I'm talking about IPD. Maybe someone else is talking about focus?
In the demo they showed a break out of the device which showed adjustable IPD width, with the displays sliding on little rods similar to many other HMDs.
