Take it with a grain of salt but Gamestop is already selling codes for DLC content for the game with the first one rumored to be called "From Dust."
The DLC has a $10 price tag but neither EA nor Bioware have made any mentions of DLC content nor day 1 DLC packs.
It could either be a mix up by Gamestop or something EA wants to hold off from revealing so that people don't get upset at Day 1 DLC.
