Yeah, it is.
I was just watching some guy's video where he talked about random stuff on/for the PS3. He happened to have a 1 minute trailer for Resistance 2 at the end of his video.
From what I have seen, its more polished, graphically, and it looks like they put more soldier units (both allie and enemy) on screen.
The video.
If your not interested in watching the full video. Wait till it fully loads, and watch it around the last 1-2 minutes.
