According to Chinese website VGSky.com, a lime green colored Sony PSP may be on the way. The lime green PSP-3000 was spotted in a factory in China. However it is not known whether this will be a prototype or actually be sent into production.
There are several potentially interesting colors on the way to U.S. soil. This includes the carnival set (radiant red, vibrant blue, yellow, and dark green) as well as lilac.
