We’ve been bringing you news for awhile now that Apple would probably be launching updates to several of their Mac lines during their WWDC 2012 keynote. Rumors have included retina displays for the MacBook Pro, MacBook Air, and iMac, as well as updates to the Mac Pro, and Ivy Bridge processors all around.

Now, with the keynote right around the corner, details have emerged of some of the specs we should expect to see in the new Macs. According to a report early this morning from 9to5Mac, there will be three configurations of the Mac Pro: two normal configurations and a server configuration. The first of the two normal configurations will sport a 3.2GHz quad-core processor, 6GB of RAM, a 1TB hard drive, and an ATI Radeon 5770 graphics processor. The second will have a 2.4GHZ twelve core processor, 12GB of RAM, and the same hard drive and GPU. The server configuration will come with the 3.2GHz processor, 8GB of RAM, and two separate 1TB hard drives.

There will also be four configurations of the MacBook Pro, 13.3-inch and two 15.4-inch. Interestingly, these appear to be only minor updates, raising the question of whether the MacBook Pro line might not be getting a retina display after all, and whether the rumored new MacBook will actually be getting the updates we’ve been expecting for the MacBook Pros.

At any rate the first of the new 13.3-inch MacBook Pros will include a 2.5GHz dual-core processor, 4GB of RAM, and a 500GB hard drive. The second will have a 2.9GHz dual-core processor, 8GB of RAM, and a 750GB hard drive. The first 15.4-inch model will have a 2.3GHz quad core processor with 4GB of RAM and a 500GB hard drive, while the second will have a 2.6GHz quad core processor with 8GB and a 750GB hard drive. The second 15.5-inch model will also offer optional upgrades to a 2.7GHz quad-core processor and a 1TB hard drive.

None of this is confirmed, though 9to5Mac’s information has often been good in the past. At any rate, all will be revealed this afternoon during Apple’s keynote. You can follow our WWDC 2012 page for more information, including live coverage of the keynote as it happens.
