Gaming history is littered with examples that caused shifts in industry focus. Since you seem totally unaware of this, here's probably the greatest example.
John Carmack's id Software released
QTest - a demo based on the soon to be released Quake using the engine of the same name. As soon as it was released it basically caused a paradigm shift in gaming perceptions for CPU manufacturers (since Quake is FPU computation heavy and immediately made Intel the gaming choice), online multiplayer gaming ( QTest has inbuilt TCP/IP multiplayer support), user performance notification ( the Turtle icon when framerate dropped), Free look / Mouselook support (kickstarting what would become the gaming mouse industry), led to the defining game benchmark used in the industry, and attracted a company called 3dfx to target the upcoming full Quake game with a proprietary API....a game and reviewers benchmark darling that virtually consigned a whole raft of graphics vendors into "also ran" status overnight.
Is AofS's Nitrous engine the new Quake? Probably not. I suspect that UE4 will shape gaming to a larger degree, but it does bring some interesting developments - developments that are sure to be replicated by other developers keen to exploit the resources that AMD's Asynchronous Compute Engines allow for (and I'd assume that Nvidia is already looking to replicate if they haven't done so already).
