Why Canon lowered the Pixel Density ?

Canon just came up with lower pixel count sensors for their Premium compact cameras.
Where are the megapixel mongers hiding when we need them. !?

Where are those insane theories and graphs showing why we need more megapixels ?!?

Canon claims a 2 EV improvement, a good sign since that is rarely heard in new compact camers releases.

Is this the end of the MP race. ?
I hope so
