Speaking to Game Informer , Sony Computer Entertainment CEO Andrew House revealed the company is doing its best to launch in as many territories as it can manage without risking a stock shortage.“You try to strike a balance, particularly for us with such a strong brand in all the European countries and across the Middle East,” he said. “We are ensuring that we have the broadest reach to ensure that people are satisfied, especially when they’ve been loyal to brand for so long. On the other hand, we’re not engendering frustration by having a shortage of supply. the company is five million units sold by the end of our fiscal year [March 31, 2014] ."Seeing as Sony has already managed to sell 1 million units in the United States alone since launching in the region on Friday , many have assumed that if you've failed to pre-order up to this point, you're out of luck. It's reassuring to discover that this isn't necessarily the case.Elsewhere in the interview, House explains why Sony isn't launching the PS4 in its home territory of Japan until 2014: it's down to a lack of software that appeals to the market. Instead, Sony is launching Vita TV in a bid to be the first video streaming providers in the region.“When we choose launch dates, we do it with very careful consideration. A huge factor in our determination is where we are seeing the appropriate breadth of great game experiences. There are just some basic differences in that highly networked experiences like online multiplay has taken off to a much greater degree in the US and European markets than it has in some of the Asian markets,” he said.“We paid careful attention to when we had enough confidence that we would have developed from the ground up experiences that the Japanese consumer would really respond to. That was the primary decision in pushing back the launch in Japan to a slightly later time period.“The opportunity for Vita TV in Japan is that you have to-date not seen quite the uptake in video streaming services that you’ve seen in many of the other countries. With a really good understanding of the Japanese entertainment consumer, we had the opportunity for a first-mover advantage."
