While I'm not spanish, my spanish chops are ok. Happy to translate what the interviews say, with proper context. First, the one that says Demon Souls has no Ray Tracing

This does lead to believe that there is no Ray Tracing on the game, contradicting previous statements and Sony themselves.
Now, the interesting bit as that another "interview" from the day before completely contradicts this.
Entrevistamos a Gavin Moore, director creativo del título en SIE Studios, encargado de coordinar tanto al equipo japonés como a Bluepoint Games.

This one shows that there is Ray Traced global illumination, from my understanding of what he said.
