No Apple computers with expandable internal storage (and no suggestion as yet of Fusion Drives for the new Mac Pro either).
It's a downside to the very few people who use it that way. When the vast majority of your users aren't actually using that space, it makes sense that they'd get rid of it. The flip side is that the pro market doesn't really have a "typical" use case; lots of people never used all those PCI slots, some people maxed out every possible slot and tray in the kit. There are certainly people being left out in the cold on that front.
Personally, I think they could have still made it very small compared to the old Pro but still sized it for 6 RAM slots and two standard 2.5" enclosures, but once they've ironed out any possible kinks I'm definitely going to grab one in a year or two. For now my 3,1 Pro has a lot of kick left in it (especially since I picked up a free Quadro 4000 to supplement my 5770.)
At least in my work environment, having Thunderbolt-based peripherals will probably save money since it'll be easy to swap I/O devices between computers, and internal storage isn't really too much of an issue since we've got a server closet full of Drobos--the only thing the two other HDDs in my Pro at work are doing is serving as an internal backup.
C'mon mini with a dedicated GPU...
Yeah now that I've got my used Pro I'm not hurting, but I was looking at the minis to tide me over for After Effects renders until they axed the GPU. Kills the appeal of them for me.
On that subject, networking AE renders seems entirely too cumbersome a process.
