The Pink PSP was unveiled a few weeks back and now at the Tokyo Game Show Sony showcased a few design concepts of the PSP. The PSP was shown in a variety of bright colors like Metallic Red, Blue and Yellow along with the military camouflage design (which sucks). Motorola started the multi color concept for RAZR line of phones followed by Nintendo for DS Lite and the multi colored products were hugely successful. So dont be surprised if these concepts become a reality.
