SCEE employee Martin has listed an unannounced PlayStation 3 on his Linkin profile, listed as ”Creative Producer – unannounced PS3 title at Sony Computer Entertainment Europe. I currently work on an unannounced PS3 title within Sony’s London Studio.”
van der Meulen had worked on games like Eight Days that were put on hold when Sony London, the internal studio based in the UK, focused development on games for the Eyepet.
It’s likely the game being developed by Sony London is in the same family-friendly genre as the Eyepet.
