There's more to immersion than stereoscopy. All the different elements of VR (3DOF tracking, positional tracking, 360 imaging, hand/controller tracking, stereoscopy) work together to flip a switch in your brain that tells it that you are in something rather than merely looking at something.
Even simply covering the entirely of your 360 range of view is enormous on it's own for flight sims. Think of the $$$ that sim enthusiasts spend on multi-monitor setups.
