Well, it looks like Gamestop.com are either copy-pasting their product descriptions or they know something we don’t, because the PS3 listing for the collector’s edition of Dragon Age Origins appears to offer an “exclusive in-game item for the upcoming Mass Effect 2”. And yes, on the PS3 version.
I’ll be honest, I’m assuming that this is a mistake, but if it’s not this is the first confirmation that Mass Effect 2 is heading to the PS3. For what it’s worth, the American special version of Dragon Age Origins also contains a bonus DVD, a cloth map and other in-game content. The thing costs $75, and doesn’t come with a set of night vision goggles.
