MacBook ProApple’s iPad 3 may not be the only device to receive a Retina display next year. A new report from DigiTimes suggests the next iteration in the MacBook Pro line will feature a much improved screen resolution as well, bumping it as high as 2880×1800.

Citing sources “in the upstream supply chain,” the Retina display toting MacBook Pro could arrive as early as Q2 2012.

While the prevailing MacBook models have displays with resolutions ranging from 1680 by 1050 to 1280 by 800, the ultra-high resolution for the new MacBook Pro will further differentiate Apple’s products from other brands, commented the sources.

Adding credence to the rumor is the expected arrival of Intel’s Ivy Bridge chipset, which would allow for 4k-resolution displays. In addition, Lion enabled support for 3200×2000 wallpapers and HiDPI display modes.

With all the talk about the Pros being slimmed down to match the MacBook Air, Retina-like resolutions would certainly differentiate Apple’s high end notebook from the competition. But is it likely to happen?

Commenting on the possibility of a Retina equipped MacBook Pro, DisplaySearch’s Richard Shim said the newest rumor isn’t that much of a stretch. “(We) haven’t seen the move to higher resolution ‘Retina’ panels for notebooks yet because the panels are new and are being using mainly for tablets, specifically iPads, but I could see it happening in the future for sure.”
