With further rumors of a larger iPad in the works – the latest one Chinese site Pad News claiming that Apple is testing several variants of a 12.9-inch iPad – we thought it would be interesting to gauge the level of interest.

The specifics of this claim fall well into sketchy territory. Pad News suggests a 4K display, which wouldn’t match iPad resolution ratios (though as the current iPad is close to 2K, something close to 4K wouldn’t be impossible). It also suggests a launch date of April – given that Apple switched iPad launch dates from the spring to the fall, switching back again doesn’t seem terribly likely.

The core rumor, however, has been around for quite some time. Several different sizes have been suggested, but 12.9 inches is the one most commonly cited. This idea first emerged back in May, attached to the world’s least likely name, and gained credibility (without the silly name) when reported by the WSJ in July … 

The idea that Apple would test larger iPad sizes is perfectly credible – the company doubtless tests all kinds of ideas – but that of course tells us nothing about the likelihood of it ever being launched.
