Yes. Colours with a "u." Some specially designed PSPs will be available only within Sony Europe's territories when the 2000 models launch on September 5th. In "Simpsons Yellow" and "Spider-man Black and Red" flavours, these new designs are clearly geared towards movie-buffs but also make a more colourful alternative to the current selection of black, silver and white.
Americans will be able to choose from "Darth Vader White," black and silver -- if you really want a garish yellow PSP Slim, you can always import.
