You add HD support, you bump up the pixel clock (heat and costs), you increase memory requirements, you increases processor requirements because it has more pixels to deal with or frame rate will sufffer, storage for the larger textures and bitmaps will increase loading time, etc... Basically you bring the price near the Xbox 360... I prefer the lower price. Given Moore's law, In a few years, it will not cost as much more to boost the mhz on all the chips as it would last year.
