A major industry shake up is set to occur today as a Reuters reports that Mattel has offered to purchased Mega Brands and their Mega Bloks line of construction toys. Mattel has reportedly offered up $460 Million for Mega Brands. By adding the Mega Bloks line, Mattel would get an immediate huge stake in the construction set market, for which they have nearly no presence. The deal would also give Mattel the opportunity to expand some of their existing brands, such as Masters of the Universe, Hot Wheels and Barbie, into the Mega Bloks line up; an area where those brands have never competed. Though there is no announcement at this time on that front.
