Microsoft is smart..

[AlkamistStar]

It's like the idea where the last thing you see/hear is what you remember...thus sometimes meaning what you consider the best...

Take a competition in dancing, or singing...if the last performance was above average...you may think it was the best out of the let's say...10 you saw before, because quite frankly you don't remember how good they were...and, "hey, the last one wasn't that bad" you may reason.

Microsoft "stole the show" so to speak by announcing their price cut last, and retailers have to now advertise their price point, and take Sony's down, or at least lessen it alot to make room for the "new". Customers that may have come into the store Friday and thought about coming back Sunday to buy a console now are teased with the Xbox price cut, essentially forgetting the PS3 one they saw, and going for the "new"...

Just my opionion as to why it was a smart move by MS..
