I don't know for either, but a quick whip round lends me to 27 Sony IPs, and 18 Nintendo IPs (if we count Mario, Mario Kart etc. as different IPs). In terms of game count, probably it's closer but I still believe Sony would win out.
As for 3rd party, I think it's Capcom, Square-Enox or Namco. Definitively one of those three.
