The PlayStation Vita hasn't sold terribly; it just hasn't become the hottest item in the video game world.
And when asked about the sales, Sony would usually say that the portable is tracking "close to internal expectations," although they have admitted that the Vita isn't doing too well in certain regions. So what are those regions?
According to the UK's gamesTM publication, we've got a pretty clear answer. As noted by The Silent Chief , a one-page feature entitled "2012 In Numbers" shows that the Vita's biggest market is definitely the US. It has crossed 900,000 sold in this country, while Japan is only just past the half-million mark (536,846). But perhaps most importantly, it just isn't performing up to snuff in Europe. It has only sold 238,429 in the UK, 218,787 in France, and 143,995 in Germany.
Maybe that isn't too surprising, but it's interesting to see the differences. If the Vita is closing in on a million in the US, that's not too bad. But Europeans aren't totally on board, it seems, and I had expected more of a response in Japan, too.
