I think there is a really big reason that people haven't mentioned yet.
Sony doesn't want their handheld to be a one off, they want it to be a line of successive systems (like the PS). I think that 10 years out Sony doesn't see handhelds being a thing anymore, getting eaten by phones and tablets. If Sony thought that the SUCCESSOR to the Vita would grab more market share, they would put more effort into the system. But, I don't think they see that happening, so they don't see a point in trying to push the Vita.
