According to German gaming site Playfront, Sony India mistakenly had the price of the PlayStation 4 listed on its website. Though the entry has since been removed (if it was there at all to begin with), the site alleges that the PlayStation 4 was priced at 399 Euro for a console packed with a 250 GB hard drive.
Unfortunately, Playfront was unable to grab a screenshot. For now, we're going to have to treat it as a rumor, especially in light of all the PS4 hype that's been generated by Sony's teaser trailer showing off the PS4 (though blurry) on video.
Sony is expected to reveal a little more about the PS4 at this year's E3. Hopefully, price point will be one of the things announced.
