Interestingly, Taiwanese publication

Since Apple demands that the new iPad model will need to be thinner than the iPad 2, while raising the machine’s screen resolution to 2048 by 1536, upstream component makers have been working aggressively to adjust the device’s LED and panel module designs to satisfy these demands, but the work has affected the launch schedule of the new tablet PC. Apple is currently giving two tablet PC projects codenamed J1 and J2 to its upstream partners for development. The sources revealed that the major differences of the new tablet PCs compared to the previous model are their size, specifications and technologies. Since the new tablet PCs have a higher resolution, Apple has demanded the design of the light source to be changed from a single LED light bar to two LED light bars on the left and right sides of the machine, but since the method of adopting two LED light bars has created difficulty in shrinking the machine’s thickness, some vendors have come out with designs that only adopt one light bar, but are packing two LED chips into one package. The sources pointed out that the J2 project seems to be an upgrade version of the J1 and although Apple has not yet decided which project will be used for the final launch, Apple is likely to make the final decision based on its needs. As for the upstream side, the component suppliers have already conducted pilot production and prepared for mass production.
believes that J2 that has been discovered in iOS 5 code is probably just the 3G model of the third generation iPad as the J2 reference was found alongside other CDMA iOS devices, but points out that they haven’t discovered references to the J1 iPad 3 prototype in iOS 5 code.
Code references in iOS software update usually suggest that Apple has already started the next generation iPad codenamed J2 with iOS 5 software update.
This report also suggest that previous reports by DigiTimes that iPad 3 will come with Retina Display and dual bar system to power its high resolution display could also turn out to be accurate.
As you can see in the image above, Apple seems to be also testing an unknown device codenamed T39. It is not clear what T39 is, but Mark Gurman of
