It's not about the software and features and stuff like that, it's about the hardware. Devs have been making games on the same systems for 7-8 years now, they have ambitions now that can't be fulfilled on current gen equipment that they need next gen systems such as the PS4, 720, and Wii U to make them become a reality.
