One week after MGS4 and BAM! right back at 'normal' sales for this year. Hell, it even dropped off faster than after GTA4. Still the only single game I have seen this generation caused a change for more than a week has been Halo 3 when the 360 actually topped the Wii in NA for almost 5 weeks (WW for 2).
