I don't believe it was ever 60fps. Previous demos were in a closed arena. There is a big difference. Anywho I wouldn't worry about the framerate...remember you're going to be fighting against a thoasand plus enemies...with them all on screen...so framerate will have to be spot on.
When I spoke about 60 fps I was discussing about the first Metal Gear Solid trailer (tgs 2005).
I'm sure that framerate in Heavenly Sword will be fixed. The answer I'm looking for is about the first playable demos showed at e3 2006 and tgs 2006, and the possibility that they did run on devkits more powerful that actual ps3 hardware. I have this doubt because I don't see an enourmos difference in detail between the new trailers and the older ones, while the framerate is much lower now.
