Yea its another phase, but not a bad one, creating enthusiasm and increasing adoption of weird and wonderful technologies is a handy aspect of the tech industry, all 3-d needs has been boiled down to 3 things, a great gpu, a 120hz plus tv, and in-expensive glassware,
Pushing 120hz tv's as a new standard will mean that anyone with a pc beneath their desk in a few years time will need to do is sort out the glasses end of things, which hopefully will have a unified solution by then.
So i dont think it will be on everyones agenda to go 3d for pc use in the near future it will be an option that will be close at hand.
