I might just wait for ultimate edition with all the dlcs ....
"The first downloadable content for Mass Effect 3 will be called From Dust, according to the GameStop database. The retailer's system lists the content at $9.99, with a release date of 6th March. That's day one DLC, folks. The sci-fi RPG hits the US on the same day.
The news comes from X360A reader Calmed Fury, who sent us an image of GameStop's database, clearly showing details of the content. However, it looks like someone at GameStop made an error and at least one fan has managed to snap the content up already.
Joystiq are reporting thatone gamer paid GameStop $10 for the DLC in exchange for a receipt with a code yesterday. Not that it's going to do him much good without the game itself, of course.
While no information is available about the nature of the content, Mass Effect producer Casey Hudson has promised both single-player and multiplayer content will be made available. You can find both the image of GameStop's database listing, as well as the receipt from that early purchaser, below.
Mass Effect 3 hits on March 6th in the US and March 9th in Europe."
