When 360 was expensive MS qas looking to be buddy buddy with fans of the Wii like: "get a 360 to complement your Wii". Though now that 360 is priced below the Wii you know that they expected it to cut into Wii sales a little more too (not just PS3 sales). As a short term plan cutting away some of PS3's sales yeah thats fine but long term this aggressively priced they want to see a shift with 360 the casual consumers console of choice.
