I think those 360 prices you listed are too high. Microsoft had lower 360 prices during black friday last holidays. I think it will at least match those prices throughout the entire holiday season this year. Also I don't see why people expect the the video game market to magically grow by a ridiculous amount after the huge drops it experienced the last two years and the even bigger drop it is experiencing the beginning of this year.
Anyway my predictions for December.
