Various sources say the Mac Pro, the iMac and the Cinema Display will get updates soon, perhaps as early as Tuesday. Look for USB 3 support to be added, and perhaps Firewire 1600/3200.
I also suspect the new iMac will sport an HDMI port. What you almost certainly won’t see is Blu-ray (which means Apple is still lagging Windows competitors in this area).
The new iMacs will probably pack faster Core i5 and/or i7 processors. I think there’s a chance — though perhaps a slim one — that a high-end iMac might come in a six-core option.
As for the Mac Pro, look for Apple to go with faster six-core Xeon processors with perhaps a “low-end” quad-core model.
“AppleInsider” (http://www.appleinsider.com) says the new rev of the Cinema Display will have a display resolution of 2560 x 1400 pixels. That sounds about right.
