Is a huge Sony device coming soon? This image from a factory suggests just that

First of all, who knows what this image could be. There have been no confirmations whether this is a smartphone, much less real. The only thing we know is that the photo above was posted on the Chinese-language Digi-wo forum by someone who claims it’s a screen for a 6.44-inch 1080p Sony “phablet” device.
Obviously this is as much of a rumor as anything, but still interesting to see what Sony may be up to. Personally, anything over 5 inches for a phone is far too much, but to each his own!
