Sony is holding back a number of PS4 consoles from its pre-order allocation, in an attempt to satisfy demand throughout the winter and early 2014. Speaking recently to Fox Business, Jack Tretton--chief executive of Sony America--said: "We want to make sure people can buy a PS4 on November 15 and through the holidays, so we're holding back some inventory to make sure people will be able to buy one."

No word on how the extra stock will be distributed globally, but the good news is that Sony is manufacturing PS4s quickly and efficiently. Tretton continues to say that "We can pre-sell every unit we can manufacture, and the good news is that production yields have been phenomenal. We're going to work very hard to make sure that every consumer that wants one gets one."

So, if you haven't already pre-ordered a PS4, but you do want to buy one for Christmas... well, you just might be in luck. This will come as frustrating news to customers of online retailers, such as Amazon, who are no longer guaranteeing newly-placed pre-orders for PS4. Tretton freely admits that Sony could pre-sell all its stock, but they want the console to be available in shops throughout the Christmas period.

Tretton continued to state that Sony sees PS4 as "the biggest launch we've ever had" and claimed that PS4 is "far and away the most powerful console ever created". We're sure Microsoft will answer back to these claims in the coming weeks.

Interestingly, Tretton also revealed several stats surrounding the launch of PS4. He claims that around 20 games will be available at launch, and 33 games will be available by the end of 2013. He also says that: "We're focused on the next 10 years. November 15 is just day one of the next 10 years for us". As with the three previous PlayStations, Sony sees PS4 as a machine that will receive support for the next 10 years.
