Prediction: The PS Vita will sell under 20m units

i think you guys are underestimating Sony's support of the system. I mean if Sony were to stop making games for vita it would die fairly quickly selling less than dreamcast probably. It all depends on how much effort Sony puts into it. If Sony will continue to release games for vita for the next 5-6 years it should be enough to create a baseline sales of about half of the PSP. To get more than that it will require 3rd party support, and not just ports.
