Even though they made a comeback with the Wii, I bet for the longest time Nintendo had to seriously regret screwing Sony over in regards to the original incarnation of the PlayStation ,that being a CD add-on for the Super NES/Famicom. Nintendo paid for 10 long years and 2 consoles before they finally overcame that mistake. I just think though, what could have been if they had stayed together and worked together as a team, instead of being bitter rivals.
