Horrible and Unlikely. Horrrible in that it would set game development for the system itself back even further. Unlikely in that it took them about ten years just to get off the PS3 and onto the PS4. Whenever Xbox leaks or announces a new console, expect Sony to do the same. It's how those two tend to play anymore. Meanwhile, Nintendo is busy scraping the bottom of the trash can for whatever remnants of dead horse content they can find.
