In a recent phone call, actually about EA's financial earnings, the EA CEO John Riccitello stated Mass Effect 2 would be available on "multiple plaftorms" and that we would see Bad Company "back on consoles" in the fourth fiscal quarter of 2009. In layman's terms that means first quarter of 2010 (January through March).
Obviously this is not a real release date, and this was all the info mentioned in the phone call. I just recently had been playing Bad Company and I am definitely looking forward to its sequel. We'll let you know if we hear of anything else!
