Someone mentioned the Unibody 17" which has most of the features missing from the rest of the unibodies. Maybe Apple thinks they can satisfy us with that, thinking the "real" pro users won't mind paying a little more, but it's way too big! Even the 15" is a little bigger than I would like (something the size of a standard 8.5x11 or A4 sheet of paper would be ideal).
Also, putting these features in the most expensive model might put off some people that don't want to spend that much (if they can afford it or not). When I bought my MBP I seriously considered getting a high-end white MB, which was the same specs at the time except for the lack of graphics card, and putting the ~$800 saved into upgrades for my Windows desktop and a nice LCD to make up for the smaller monitor. Now the price difference between the base 13" MBP and the cheapest model with expresscard and antiglare is $1300. If you only want a real GPU and can live without antiglare and expresscard, it's still $800. That's a lot of money just for a GPU. (I know you get other upgrades like more memory and drive space for that money, but it's a lot cheaper to upgrade those separately.)
For me, a docking station would be great. I mostly only need high speed connectivity at my desk, and I typically have enough cables plugged in that sometimes I don't take my MBP with me because I am too lazy to unplug it. Right now I have 3 cables on either side--power, headphones, and eSATA on the left and ethernet, FW800, and USB on the right. With the cables sticking out the side, all the space next to the computer isn't very useful, so I tend to accumulate pules of stuff there right on top of the cables, instead of using the space for more useful things like papers am working on or a mouse. I know BookEndz makes a dock, but it's really a hack and it does not add a whole lot of functionality.
