When DX11 has either been 1) The standard for a fair while/DX12 is a huge leap or 2) When next generation consoles are out depending on their tech.
Doubtful. These tech demos serve to show what current technology
can do if it's dedicated to a single thing. We could have hyper-realistic hair like that now, but not alongside a game world and with it on the heads of countless NPCs all at the same time. As for next-generation consoles, something tells me that they still won't even hold a candle to today's current PCs. Cost efficiency and whatnot.
