When will –12V go the way of –5V?

I'm guessing it will happen about 3 to 5 years after PCI slots, along with the headers for COM ports, are out of the mainstream. Any subsequent device that really needs a negative supply (or specialty mainboards retaining the legacy connectors) can just generate one from a positive supply with a buck-boost converter — as HDDs have long used to get a –5V supply for their head preamplifiers. Any other ideas?
Information is far more fragile than the HDDs it's stored on. Being an afterthought is no excuse for a bad product.
