Aside from creating Singstar, Sony Computer Entertainment’s London studio spearheaded the EyeToy and other camera controlled games such as EyePet. With their past experience, it seems like SCEE would be the division to pioneer software for the upcoming PlayStation 3 motion controller.
Maybe Razor, The Shoot, and Wonderbook are their motion controller projects. Sony Computer Entertainment Europe trademarked those names in Europe for use with computer video game programmes.
Wonderbook has an extra descriptor. It can also be used for “toys, games and playthings; hand-held electronic games; electronic educational teaching games.” Motion controlled edutainment PlayStation 3 software, perhaps?
