Yeah, they're in financial trouble, but man have they invested tons of money creating new IPs for their different platforms these last years (Vita+PS3). And they continue doing so!
Some of the games I remember right now:
-Little Big Planet
-The Last Guardian (one can dream)
-The Last of Us
I never really enjoyed the PS2 era but I'll make a guess and assume it got plenty of new IPs too, like God of War and Killzone.
Thanks Sony, for pushing out new and creative first party games, even if they don't end up selling like Halo or COD.
