Although sales figures from the United States show the PlayStation 3 is currently being outsold by its rivals, a US based sales tracker has said the machine is ahead of Xbox 360 in real terms.
A spokesman from NPD, a respected sales tracking firm, said, "figures show that the PS3 is selling slightly faster in the US than the Xbox 360 did at the same stage in its release".
After a delay of more than four months, one million PlayStation 3 consoles went on sale from midnight across Europe, with over 200,000 available in the UK.
Although current UK figures show the Nintendo Wii is outselling all other consoles at the moment, one analyst believes Sony can become number one if it releases the right games.
Gartner principal analyst Paul O'Donovan said, "The real issue for Sony is whether they can get back the momentum they had with PS2. The only thing that is going to drive that is the number of titles available".
