It's been rumored for some time now that Samsung has been working on a larger tablet for the education market. On Friday phoneArena reported that a photo of Samsung's upcoming 12.2 inch tablet reportedly was leaked to a Korea website and that it could be shown as early as the CES tradeshow being held in Vegas in January. The educational market is one that Samsung has had their eyes on for some time now as a new Samsung patent filing revealed last week.
In November a Google patent application came to light or a new UI for larger tablets specifically for the educational market. Then last Thursday Patent Bolt discovered a new Samsung patent application that was published by the US Patent Office relating to a new e-Chalkboard system for the education market as their patent FIG. 1 notes above.
