Ray Muzyka has been spilling some Bio-beans over on Eurogamer today. In the public interview, he says that while there is both PDLC (the "P" stands for "Premium") being developed for Mass Effect 2 and expansion content planned for Dragon Age: Origins, most of the core team for the sci-fi series has already started working on the as-yet-unannounced Mass Effect 3. He does promise that there's been a vision from the beginning and that the vision has been tweaked and changed as the games are coming along, so hopefully the trilogy will lead to a worthwhile conclusion.
He also hints that there's lots more to see coming from Bioware -- Muzyka is working on both PS3 and 360 titles (some still secret) "across the studios I manage," and of course The Old Republic, which he describes as "KotOR 3, 4, 5, 6, 7, 8, 9 in one project," is in development as well. And at the very end of the interview, to a question about what we can expect at this year's E3, he only answers a cryptic, "Yes!" Maybe Muzyka should have been in charge of the dialog trees in Dragon Age; the game would have been a lot shorter.
