PlayStation 3 Goes on Sale

Gamers and entrepreneurs prepared to shell out $500 or more for the new PlayStation 3 console that goes on sale Friday, many of them after waiting in line for days despite the likelihood they'd go home empty-handed.

Sony promised 400,000 PS3 machines for the United States on Friday and about 1 million by year's end. Worldwide, it was expecting 2 million this year, half its original projections. Sony has already delayed the European launch until March.
