Remind me again why Modern Warfare 2 is supposed to be a day one purchase?

MW 1 graphics good you sir need your eyes checked. it was like PSone textures in some area's like the sneaking hay field
and the faces had less polygons then some PS2 games.

They were good enough for me overall.  So, how does addressing those make MW2 a day one purchase?
