User blog comment:Bronzey/Christina Norman hints at another Mass Effect game for 2011/@comment-114.76.43.204-20110110232706/@comment-730941-20110113165426

An update: it appears from his Twitter page that Houston's "special project" was just the downloadable (PSN, non-disc) version of Mass Effect 2 for PS3. I have no idea why it would need someone to work on it for so long, but there you go.

Still no word on Christina Norman's, however.
