Furthermore, the point of the thread was not to single out people, but to single out the ridicules idea that MGS4 will make a drastic, permanent change in PS3 sales.

 Euhm okay :). But the sales of the PS3 has already changed the last year dramatically.  Search how much the PS3 sold like a year ago and how much it sells now;.

 
I searched it for you.

One year ago the PS3 sold weekly around 60K.


Now we see weekly sales of 150k...
