The Mac Pro update was a small CPU upgrade. That’s it.
However the above tweet gives me a little hope that maybe Apple has something bigger on the horizon. If Apple was really going to drop the Mac Pro, not being able to get the older CPUs would be a great time to do it … why go through the testing process for the “newer” processors when you can just drop the line that you plan on killing anyway.
I have no idea what is holding Apple back from rolling out the new E5 Xeons, but I still hope that they roll something out. Mountain Lion is due in July, so maybe the desktops will get their updates then (the iMac and Mac mini were also sitting on the sidelines today).
