It's about that time, folks. With the iPad 3 launch likely set for late March or early April, an influx of rumors and leaked photos are primed to make an appearance. That said, an image spotted on a Korean message board purports to show an iPad 3 Retina Display juxtaposed against an iPad 2 screen.
In the photo below, the iPad 3 screen is on the bottom.

While the two screens, by and large, look the same, the purported iPad 3 screen has 3 connected cable attachments which link up to the circuit board.
To this end, Mac Rumors notes:
The claimed iPad 3 photo shows 3 wide ribbon cables that might be used for data. The iPad 3 is expected to carry a high resolution screen of 2048x1536 which is four times the number of pixels of the current iPad 2, so the need for additional data bandwidth would be understandable.
As for other iPad 3 news, it's been largely quiet on the rumor front, save for a report last week claiming that Apple was working hard to launch the iPad 3 on February 24, Steve Jobs' birthday.
While potentially exciting for eager iPad 3 owners, moving up production by a full month is challenging to say the least and requires the coordinated cooperation of many component suppliers. That being the case, I imagine the iPad 3 won't see the light of day until April, or late March at the absolute earliest.
