All good news, but I think we can realistically say that this will be the last upgrade before it's killed off.
Where have I heard that before?
That doesn't seem realistic at all! If they have spent resources making "something really different" it makes no sense to kill it off after its one and only appearance.
Exactly.
It's just going to be a LOT different.
My prediction: It will be basically modular in some way, build as you need type thing, I'm thinking like a big, stackable Mac Mini. Probably will work with any monitor or plugged up to another Mac. And within five years most professional workstations aimed at the creative markets will be a version of the new Mac Pro line, much like tons of laptops are copies of the MBAir now.
Either that, or they'll just toss the optical and ad a couple more drive bays.
