The game isn't out yet in Europe. Has it been released in the US?
In general: It's because the market was over saturated with Brain Age clones: We had English Training, Eye training, Big Brain Academy, countless of Ubisoft games and even games with the same name on PSP. It's the same thing that happened to Guitar Hero! The genre / IP didn't suddenly implode like the OP suggests. It was a slow decline caused by a truckload of rip-offs.
