However, on the original point. I think probably the bigger part of this fascination with this particular game is that Sony ponied up cash for an exclusive that is clearly inferior on PS3 (graphically) compared to X360.
(...)
I can only think that maybe Sony were shown a build running on X360 or PC and were lead to believe that the PS3 version would be similar?
I wonder if it would have mattered. I suspect it went like this:

Sony Pictures: Hey, Atari. How's it going?
A: Hey! Not bad.
SP: You know, it's really important that the Ghostbusters game launches together with the Blu-Ray, on the anniversary. How's that going?
A: We're fine for NA! But having a few hitches in Europe, we're sorta liquidating our holdings, not sure we'll make it...
SP: Really? That sucks. Tell you what: since I own the IP, I'll get my sister subsidiary to publish the game for you, so we meet the deadline.
A: Great! All versions?
SP: We're only going to publish the Playstation versions. You can hold onto the rights for the other ones.
A: Well, better than nothing. Okay.

I imagine that there may have been some contract-waving and legal posturing as well. Of course, if we believe in moneyhats, it goes:

Sony Pictures: Hey Atari, how's it going?
Atari: Hey! Not bad.
SP: Your Ghostbusters game is a couple of months away from release, right?
A: Yeah...
SP: I was thinking... maybe we should make it an exclusive. My sister subsidiary will publish it for you. Don't worry, though: we'll pay.
A: E-exclusive? But--
SP: Well, timed exclusive. How much would that be?
A: <number>
SP: *checks pockets* Dammit, I don't have that much on me. How much just for Europe?
A: <number>
SP: I'll take it!

Or maybe Sony went up to Atari and asked specifically for exclusivity in Europe.
