Squaresoft didn't choose Sony because of the CD. The truth is that the relationship between Square and Nintendo were bad at the time.
Square was angry that Nintendo favoured Enix with the bigger cartridge and after the ( relative ) success of FF6 even in USA want to have privileges.
The relantion was so consumed that with Super Mario RPG the pact was that Square would have published the title in Japan ( the biggest market potential for JRPG ) while Nintendo would have published it in USA.
Nintendo broke the pact and published it in both markets ( 1.5 million in Jap, 0.5 in USA ).
Then Square released the last 2 titles in development on Snes in Japan and jumped at the Sony ship starting to made negative comment about Ultra64 (N64).
Yamauchi was so furious that bannished Square from every Nintendo systems until 2002 when he stepped down.
