Several sources claim Sony may have a couple of problems with the upcoming PlayStation 3 console.
One source claims the PS3 is still full of bugs and won't be ready for its release in March:
The deep throat has a bit of credibility for coming out with some deep on market intelligence earlier in the year, so there might be something in what he says. The bloke claims that he had hands on experience with a prototype PS3 and it left much to be desired for a product that is supposed to hit the shops in a few months.
Additionally, Kotaku claims the PS3's graphics engine also got some problems. More info at The Inquirer.
