What system would it be on though? It is a shame Sting didn't do the things Strum suggested for the PSP version in the first place, I'm curious about the past of the Grim Angels as well (Did Hector ever give a reason why he wanted to become an almighty being? I haven't played for a while and I don't have my GBA anymore.)
I don't know about Sting, but Capcom did a good job animating and creating anime cutscenes for the Maverick Hunter X series on the PSP. The opening scene of Tales of Symphonia by Namco was nicely done too...
