Actually, PS3s can switch resolutions depending on the game. I made the mistake of ordering DMC4 PAL version for my NTSC-J PS3, when I loaded it up, it palyed the game in PAL resolution. Same thing happened with a friends PAL PS3, where he booted up NBA 2k8 and it loaded in NTSC.
That is if it will even get ported stateside. I've a feeling this one is staying in Japan.
Also, more screenshots.
