At least for now is safe to assume that Dark Souls II and Versus XIII are gonna be released on PS3 next year. The Last Guardian can go either way if is released on PS3 or 4 really...
There's also 'Project Zwei' from Tango Gameworks that is supposed to come out at the end of this year for Xbox 360 and PS3, but platforms hasn't been officially announced so far.
Oh and Persona 5. Is not crazy to think that is gonna be "revealed" at TGS or Famitsu and drops on the PS3 with the PS4 released, it can totally happen and can't imagine many people getting mad at that.
