I may not have copy but link OP posted does.

Here's Digital Foundary blurb...... they seem to think the version is not definitive and no better or worse than the Xbox 360 version in terms of graphics or gameplay. But its still a 10/10 game!

"Between the consoles, the gap narrows. Technologically it still feels like the Xbox 360 version has the edge, but occasionally lower frame-rates and mostly unnoticeable graphical compromises on PS3 are not going to have much impact on the fun you have playing this game. Scored today, this would still be a 10/10 game on both platforms.

However, in putting together this feature, the opportunity to return to Mass Effect 2 simply serves to remind us that the experience of playing this series is so much more than just one game: it's a saga, an epic series quite unlike any other where all three chapters are interlinked, and unfortunately, due to licensing agreements, the Xbox 360 is the only console that gives you the full story."

So, it eliminated jitter and tearing. A welcome fix.

Today in NA

in the digitalfoundry video the ps3 looks better but not by much it looks like the gave it an extra week of polish if someone told me this was on a different engine id say your lieing
