Alright, scans are back up, for the 10th time -- goddamit, I'm already sick of DMC -- Too Human here I come!!!
Anyway, the engine Capcom is using is utilized first on 'generic' PC -- the 60% of developement, and then afterwards, the game is utilized for the specific hardware (in DMC4's case, the PS3).
I think this final year in development when Capcom specifies development for the PS3, they'll had in the more fancier things.
Keep in mind however, that things like motion blur can only be seen in video -- so, we'll wait on that.
