I\'m not sure where all these release date rumors start... but here\'s the speculation:
In spring of 2005 the Sony PS3 preview trailers ended with "lauching spring 2006". No word on regions, or exactly what spring is.
March 2006 is a good bet for that, and most people are guessing that it will be initially a Japanese launch, but it *could* be a worldwide launch. Assuming a simmilar timeframe to the PS2 (launched Japan march 2000, NA October 2000, Europe November 24, 2000), we will probably see the PS3 in North America and Europe before christmas.
No other definitive dates have been forthcoming from Sony or their trailers. Sony mentioned the other day they were buying the central stand (normal) at Consumer Electronic Show (CES) in January 2006 (what\'s unusual? The platforum will have 12,000 sq. feet - aprox 3660 square meters).... so expect big news there.
No firm estimates for price are out there. The amounts CNN reported last week of 300-400 US as said by Sony\'s CEO (saying they would sell it at a loss if necessary to ensure Blu-ray market penetration) turned out to be a false rumor, but guesses are that they will aim for the same price point as the XboX, even if it is a loss at that price.
