"How much innovation can the end-user handle?" - Shawn Layden explains why he said Sony should have made PlayStation Portable 2 rather than PS Vita

Former PlayStation leader Shawn Layden has elaborated on his recent comments that Sony should have made a PlayStation Portable 2 instead of the PS Vita. Layden argued that Sony overdid the feature-set with the Vita, including additions like back-touch, an OLED screen, and proprietary memory cards, which drove up costs and ultimately hurt sales. He suggested that a PSP2 would have simply been a PSP with an additional analogue stick, addressing the main complaint about the original. Layden also discussed the concept of a "value proposition" in game development, using Gran Turismo as an example. He noted that the series went from 65 cars in the first game to 290 in the second, with each car having associated licensing and design costs. He questioned whether the time spent on packing in more content value might have been better spent on other features, as the value proposition can become "out of whack."
