No PSP redesign planned, but more colors proposed

During a GDC appearance, Sony PSP senior product manager John Koller continued to thwart off rumors that a redesign is the works. It seems that Sony is particularly interested in denying plans to reduce the handheld's overall size, especially its screen. The current strategy is to stay the course; to generate interest in the existing model. Which means? You guessed it: tapping into some of that unused real estate in the ol' rainbow. Handheld owners are known to purchase multiple units, explained Koller -- especially when there are new colors on the market. Why expand your consumer base when you can continue to re-sell freshened up old goods to the same customers? (Wonder where Sony got that idea...?)
