In addition to the recent price-drop (sometime in March) for its wireless 3D Vision glasses, Nvidia today added the wired option as well.
Everything remains the same except for the fact that this time around, you will will not have that much freedom when it comes to moving your head around, courtesy of the USB cable. The original bundle should still be selling for around US $149 while the extra wireless glasses should be selling at around US $119, which is still a bit more expensive than the new wired solution.
Since displays with support for 3D Vision aren't that rare these days, it sounds like the right time to introduce such a product. The new wired 3D Vision glasses should be available pretty soon with a suggested price tag of US $99.
