I think that it'll be a cut-down version of the old tower, not the entire huge thing. My prediction: 2 16x PCIe card slots: YES 2 4x PCIe card slots: NO, use Thunderbolt 3 instead. Every time Apple can push a device maker to switch from slow PCIe to Thunderbolt, that's another device that's usable with a MacBook Pro. 4 3.5" hard disk bays: NO 1 3.5" hard disk bay: MAYBE 2–4 PCIe Flash storage bays: YES 2 optical/Zip/floppy drive bays: HELL NO. Most users rarely use optical discs, and almost no one uses both bays. An external drive is actually more convenient, because you can put it somewhere on your desk when you need it, and put it away when you're done. Then you can place the tower wherever you like, because you won't be stuffing discs into it. In addition, ever since the Blue and White G3, Apple has had to rig up some doors to hide the off-white plastic of the optical drives. Never again! The starting price will go back to $2499, like it was in 2012. The B&W G3 started at $1599, $2340 in today's dollars.
