I feel like overclockability is the last thing Nvidia should be focusing on for laptops. The trade-off for overclocking is heat generation which is undesirable for laptops by far. These cards generate a lot of heat as is.
I probably won't buy one of these. I'll probably just stuff my desktop into an aluminum case suitcase. But you could pull the battery out and throw it away for all the VR folks care. This will get setup on a table at conferences by a lot of people.
