BitMob reports that an anonymous source claims the words "PlayStation 4 in 18 months" were uttered during a "high level meeting" at Sony. Sony, naturally, responded with the usual "we don't comment on rumors and speculation" so beloved of tech companies and so frustrating to people actually wanting answers.
BitMob's reporter Rus McLaughlin believes that the source from Sony is reputable and trustworthy, but has his doubts over whether the company is really likely to launch a PlayStation 4 on the world within the next 18 months.
