Microsoft did take the existing console market and adjust it with the 360 by introducing different SKU's, this we know.
The production of consoles like computers, offering different price points is genius. The ability to alter a console without completely coming out with a new one is amazing when compared to past generations. This makes me think this generation will last much longer than any before it.
Point is that because of the need to develop new SKU's (whatever that need may be- price/low sales) Sony is adapting very fast to its companies needs.
Because of the multiple SKU's the console market can refine itself as time goes on.
( I know that you all know this, I just find it pretty amazing)
