My take on Sony rumors is that they are rarely accurate unless the actual camera is a month away from being formally announced. Generally though, when the Alpha community has rumblings about a new camera, it means something is on the horizon (of course, they typically guess the wrong thing entirely).
As far as this specific rumor goes, I don't think it is likely, but then again, not even Sony
knows what Sony
might do next
Come on dude, we all know you're the source. We know you work for Sony, so come clean and tell us what you know!
