PlayStation 4 represents possibly the single biggest leap seen in a console generation

[Jon-Erich]

Based on the thread title alone, I call bullshit on that statement. This guy obviously doesn't remember the transition from the 16 bit era to the 32 bit/64 bit era. The industry literally went from two dimensional sprites to fully functioning 3D worlds overnight. Within the transition of a single generation, gameplay had to be re-invented. New genres were created. Old genres died out. It was the 5th generation that was and probably always will be the biggest leap in gaming history, not the 8th generation.
