There is no way LBP / Res2 / GeOW2 / Fable2 / Banjo / Fallout3 are going to sell under a million copies before christmas. Infact it is likely they will all sell over 2 million before Christmas. Gears2 will probably sell 4 million by Christmas by my reckoning.
Left4Dead might be a potential because Valve are still traditionally seen as PC developers. I hope this does well on the 360 though. Financially it wont be a flop as porting a game based on the source engine from PC to 360 does not take valve very long but it might not sell 1 million copies.
Infact as someone else has said the lineup looks pretty good to be fair leading up to Christmas. Unforuantely it might be a game like Dead Space which under performs even though it will probably get good reviews.
The truth is that there are crazy sales around Christmas so a lot of games are going to sell big numbers. Its just a surprise that none of these big games are being released pre christmas madness like in September / early-mid October. As GeOW2 would sell big whatever its release but releasing in November might eat up sales of other games.
Your In the Movies look rubbish as well so its probably going to sell rubbishly.
