The PlayStation 3 got off to a rocky start and is now only number three in next-gen console sales, but Sony claims it is happy with its current status in the market.

NPD sales data reported yesterday that the sale of 243,443 units in North America during January contributed to a record $550m in revenues. Strong sales of the PlayStation 2 and the PlayStation Portable, which sold 299,352 and 210,719 units respectively, was also a major factor.

"We are pleased with the numbers from January as they demonstrate overall sales improvements for our legacy systems year on year and continued momentum for PS3," claimed David Karraker, Sony Computer Entertainment's director of corporate communications.

"With supply levels stabilising, you can expect to see increased marketing for PS3 and PS2 in weekly retail circulars, which should garner strong numbers, boosted by big software launches, such as MotorStorm and Virtua Fighter 5."

Another bright spot in Sony's near future will be the release of the heavily-awaited God of War 2, which launches in shops next month for the PS2. Sony is also expecting strong results from PSP titles such as Ratchet & Clank: Size Matters, which has already debuted this month. Karraker also claimed that the PSP's impressive January hardware sales are "quickly closing the gap on the leading competitor".

All in all, Sony is pleased with the overall performance of the PlayStation brand, claiming last month's figures to be "the biggest January sales in the history of the company in North America."
