are we going by Western releases mostly? If so here are a few additions for ya in the third party category:
Legasista: developed by System Prisma releasing 8/21/12
Mugen Souls: developed by Compile Heart releasing 9/18/12
The Witch and the Hundred Knights: developed by Nippon Ichi Software releasing Q1 2013
Ni no Kuni: developed by Level 5 releasing Q1 2013
Atelier Ayesha: developed by Gust, will probably release 2013 but isn't announced for Western release yet
Also I'd define LBP Karting as 2nd party since it is paid for by Sony and it's a Sony IP with a third party developer. Important thing to remember is that there aren't any 2nd party developers, only 2nd party games.
