Right, I kind of figured it was all the minds "uploaded" and becoming a kind of "universal consciousness" or gestalt consciousness. The game never really states that the minds are placed there, but with the article entry and Legion's statements at the end of ME2, it opened up that possibility. Truth is, I like this explanation. Makes it even more horrifying to a certain extent.
