iPad 3 Retina display iBooks

BGR was tipped on a few references to x2 iPad graphics -- the kind required for Retina displays -- in the new iBooks 2, adding fuel to the iPad 3 rumour fire.

Some of these aren't new, and were included in the iBooks 1.1 update from last year, but it's still nice to see that Apple's getting ready.
