When the Wii and DS were new, I remember reading interviews from Nintendo where they talked about keeping development costs low (and ensuring that small developers could be sucessful) was one of the core reasons they used the hardware they did. At the same time I remember a Sony executive saying something along the lines of 'If developers can't afford to make visually impressive games for the PS3 they can always make PS2 games' ...
Small developers can have a large impact on a platform but they have a low success rate so you need a lot of them, trying to attract them after the platform is struggling isn't going to work well, and it will be years until those Sony does attract are able to release anything. In other words, Sony's on the right tract they're just 36 months too late for the PS-Vita.
