Hmmm you post this for XBOX 360.
9) If Sony drops price again will 360 be outsold - routinely - by PS3 worldwide?
Why no post for PS3
9) If MS drops 360 price will PS3 again be grossly oversold by the 360?
In all likelyhood MS is in a far better position to cut the price of the 360 to boost sales. There is a good chance that the 360 Arcade will be $199 when GTA IV releases.
I am glad you didnt bring up Killzone 2. It is nuts to me how much that game which is a sequel to a game that did not create a big following is thought of as a system seller.
Libraries sell systems not individual games
