If Sony doesnt cut the cost of the PS3 before Christmas

[Nidan]

Then effectively the will always be around $100USD more than the Xbox360.

So my point is does MS force Sony to make the cut, and lose around 1/2 Billion dollars in the next 12 months (based on 10 million consoles) and extra losses throughout the life of the PS3?

Or do they leave MS to a gap of $100USD?

Now how effective is a $100USD gap in 2-3 years when the cost of bluray is much less?(ie close or under $100)
