AppleInsider is reporting that Apple is preparing to launch a 27-inch Cinema Display and 12-core Mac Pro by June. The 27-inch Cinema Display is rumored to use the same panel as the one used in the 27-inch iMac and will look similar to the 24-inch Cinema Display launched in October 2008.
Internally, the display is referred to as "K59" and AppleInsider's sources believe its been lingering in Apple's labs for some time while Apple waited for the larger LCD panel – which supports resolutions up to 2560 by 1440 pixels – to drop in price.
Along side the 27-inch Cinema Display will be the long-awaited Mac Pro update. The tower would get at least one 12-core model using two of Intel's six-core Xeon 5600 processors (that's a dodeca-core Mac Pro, baby!). The 5600 series will be available in 2.66, 2.8, 2.93, and 3.33GHz configurations.
A June time frame would be almost fifteen months after Apple shipped the last Mac Pro. The late release would owe itself to Intel not delivering the Xeon 5600's for another month and a half. Apple typically updates their Pro towers in the first few months of the new year.
