My take - B+/A-
Sony will be fine in the West. Sony will take alot of the customers 360 is going after when the price drops. I was curious to see if Sony would have anything to try to get some more support from Japanese gamers/casual gamers to justify the price..no dice (granted this is an American centric event now, not a worldwide event)
A true price drop would have helped alot this year (remember most consumers don't care about the added value - $499/$599 is the same as last year). Because of that, I see Nintendo and Microsoft trouncing Sony in 2007.
In terms of appealing to the three markets (and how I expect sales to be through the holidays):
Console Japan Americas Others
Wii A B+ B
PS3 D+ B- C+
Xbox 360 D- A- B-
