Mass Effect kind of reminds me of Knights of the Old Republic, and since that game did about 1.46 million in North America (possibly higher with the greatest hits) I'd guess that Mass Effect will do similar numbers (probably about 1.5 million).
I think Eternal Sonata will do better than the 195,000 given at the start of the thread, I'd put it at around 350,000.
I think you're right with the 450,000 for Two Worlds since it's likely to ride on the coattails of Oblivion.
Lost Odyssey and Blue Dragon I find hard to even try to predict. Lost Odyssey appeals to me more and since I consider myself a typical Xbox 360 owner I'd say it'll likely get more sales than Blue Dragon.
