Ohh right, because before the Vita was released, it was easy to gauge how difficult it was to port games to the Vita, and know how little Sony was actually going to support that platform. He was supposed to know how a lot of Sony's plans for the platform were going to fall through. Of course. What an idiot. The article is about the Vita's potential, and it had a lot before it was release. The potential was just wasted. What an asshole.
The article was posted in October 2011. At that point in time it was already known that the Vita wouldn't get Monster Hunter. Launch lineup was known. Price was known. The competition (Nintendo) was known.
At that point anyone who wasn't a complete Sony fanboy could tell that the Vita would not outsell the 3DS.
It's ridiculous that you even try to defend him as someone who is credible. Your first post started by saying that he is a Nintendo fan when the evidence we have points towards a PS fanboy. He's not just biased, he's incredibly biased. Hence why his Vita prediction was so off.
