I'm very supportive of Oculus deciding to focus on one platform. Though I'm a Mac and Linux user, I want Oculus to be a success, and deciding to say "no" to non-dominant options maximizes that chance. Relatedly, can anyone give an estimate about how many years behind integrated graphics chips like Intel's are from Rift-compatible performance?

Lets do some basic math to get some clue of the future. I welcome others to provide more detailed analysis to adjust my calculations. The nVidia GTX 970 has 3494 GFLOPS[1] of single precision processing power. The strongest currently available Intel integrated GPU (Intel Iris Pro Graphics P6300, GT3e) seems to have around 1000 GFLOPS[2] and is from November 2013. The September 2012 Intel Iris Pro 5200 has 832 GFLOPS[3], and the April 2012 Intel HD Graphics 4000 has 333 GFLOPS[4]. The pace of improvement seems to have slowed down for Intel. Given a generous 25% YoY growth, Intel will have a 3500 GFLOPS integrated GPU somewhere around 2020. There is high demand for mobile performance though, so with additional investments, perhaps a 33% YoY growth for performance-per-watt can be achieved? Then a 3500 GFLOPs integrated GPU could arrive as soon as end of 2018. Even so, if VR is even mildly successful, I can imagine nVidia & AMD pumping out even bigger behemoths than the currently available 6144 GFLOPS[1] nVidia GTX Titan X. These giants will also receive annual performance gains, so the gap between heavily cooled desktop beasts and cool mobile parts will probably remain similar.
