Well actually it is just the alloy casing of the iPad 3 which has been spotted and it gives away a few more clues as to what the next generationiPad will be sporting when it is released (next month?)
If you are reading this, then you will obviously have some vague ideas as to what the iPad 3 is likely to have once it is finally released.
A better screen option seems likely, but will only be available on a higher more costlier iPad 3 models. Other likely upgrade candidates are a faster quad core A6 CPU, better cameras and a larger battery.

Well the alleged iPad 3 case above actually confirms the existance of a new type of display, by way of new mounting hardware, the newiPad 3 case is also said to have modified areas for a new camera, a new mounting area for a smaller logic board and is said to offer more space for a larger battery.
On the design front, the iPad 3 looks like it will have a very similar appearance to the current iPad 2, albeit slightly thicker to accomidate the larger battery.
