I dont see it happening soon as 2k Games are working close with Microsoft and it was touch and go at first if even The Darkness would go to PS3. If it did happen it wont be for a while yet and most people will own 360 version before hand so sales of PS3 version wouldnt be close to 360 versions. It would be a similar story to that of GTA when it appeared on Xbox. It came out 6 months after PS2 version and as the Xbox hadnt sold as many consoles and most people already owned PS2 version the sales figures differed drastically. I wouldnt mind it happening as more sales for each game means more money for the developers and better games for us.

very interesting
