At Leipzig, Sony announced a limited-edition pink PS2. They also announced price drops to the PS2 and PSP.
OK, the pink edition is VERY cool. I'll give them that. But the "appeal to a wider demographic"? I'm not sure the demographic of people that (a) are interested in a game console, (b) find games among the catalog appealing, and (c) wouldn't buy it because they wanted pink instead of black and silver, is very large. My guess is that you will see a fair number of units move, but they will be repeat buyers.
