No, Not ever.
Playstation brand has always pushed innovation in hardware and has always tried to bring the most unique and varied New IP's to their playstation consoles. Add to that that prices of games are reduced in a timely manner.
Nintendo has lacked in these 2 aries for many many years now.
This kind of merger would hold Sony back and drive gaming into a stale ( same old same old ) routine.
Sorry, but no way.
Seriously? More power does not equal innovation. Nintendo takes more chances with hardware.
I actually would like to see a merger. I would prefer a merger over Nintendo going 3rd party.
They would have both great home console and handheld devices.
