Well, I can tell you that if one of those pics in particular is from a realtime cut scene, there simply is no doubt this is the best looking PS2 game. However, to be on the safe side, I'll assume it's pre-rendered.
All the pics are taken from some VHS video material, and are really grainy and blurry, with colors obviously messed up. What can be seen though, is that there's a LOT of detail. Everything looks very busy, very packed... I'd be really surprised if this game manages to keep even steady 30FPS, simply judging by all the stuff they seem to be throwing on the screen (one thing in particular, if I see it correctly in all this blur, has definitely never been done on PS2 before)
