BioWare: You Won't See a Difference Between ME3's Versions

I admit I'd be more surprised if BioWare had actually admitted that there are going to be differences between the various versions of the game, but BioWare's director of marketing David Silverman told CVG that we won't see "a drop in quality" in either the Playstation 3 or Xbox 360 version of the title. Here's the relevant quote:
Discussing Mass Effect 3's arrival in March next year, BioWare marketing boss David Silverman told CVG: "This is the first time that all three platforms have shipped at the same time and it will be an amazing adventure whatever platform you play it on. I don't think you'll see a difference between the Xbox version and the PS3 version. There's no drop in quality on either."
