Will Barbie's latest makeover turn round Mattel's fortunes?

Is the plastic princess losing her shine? Last year Mattel lost its crown as the world's biggest toy company when it was overtaken by Lego as the globe's most profitable toy maker. On Monday it announced the CEO had left the company after over a year of falling profits. And it's all linked to falling Barbie sales. Now she's undergoing yet another make-over - so will Barbie the superhero help turn Mattel's fortunes around?
