Not much here.
Also your history is a little bit off when it comes to the Zelda CD-I games. Nintendo originally contracted with Sony for the development of a CD add on for the Super Nintendo, this dea fell through. Sony took the technology and developed the Playstation from the ashes.
Now, afterwards Niintendo contracted with Phillips to build the add on for the super Nintendo. This fell through also, but Philips had already developed a trilogy of Zelda games for the Philps CD-i system. The Philips CD-i was based off the technology that would have been the CD add on for the Super Nintendo. It was Philips Corp. that developed these games not Sony. So your conspiracy theory kind of falls short on that one.
But I will agree the games did suck.
