I think that after all these answers we can agree on these 2 points:
- Prosumers (that are the real target of this new MBP) can sit just fine with the 15" config capped at 16Gb and a not so powerful GPU that could have been the 950M. Be honest, you don't need specs beyond these;
- Professionals would have loved to have 32Gb -AND- a 960M as gpu (at the very least) for the top config;
Everyone here wanted an nVIDIA card, obviously. And with the above i think a big fat 60% of the replies in this thread would disappear.
And it would really be worth the amount of money they are asking.
That's pretty much hitting the nail between the eyes

I've said it myself, the target market for Apple devices these days are general computer users not the really demanding user, has been for quite some time. Now that Apple is as large and popular as it is, they don't need to focus on the pro market, the general consumers and prosumers are a much larger market than the rest of us. So that's naturally where they are going to focus their attention.
Still, it is a bit of a shame that they aren't even offering the option of catering to the more demanding market. I know there are those who say the previous MacBooks had a 16GB limit and we were fine with that, so why not now.
The trouble there is, at the time 16GB was enough, just. Things have moved on, our processes have naturally become more advanced and with that, more demanding. So while 16GB may have been fine four years ago, it's not so much now. But we're the minority now and I do think that the refresh next year will add more RAM as an option.
In the meantime we can either wait, or if we really want it, we can cope with 16GB. As much as I'd love more in the MacBook Pro just now, it would be foolish to say that 16GB is completely unworkable. It's a mobile system not my main workstation, I can absolutely adjust my workflow to compensate for the lack of RAM and keep the really intensive stuff for my main system.
That's also the beauty of being completely connected. For years I've been working towards centralised files and complete local and remote access to everything I have. Every file, printer, 3D printer and so on and so on, is connected to my network and I can access everything from anywhere. So there's no reason I can't work as best I can on the MacBook and when I need a bit more grunt. Just fire up Remote Desktop software and transfer the workload to my main system. When it's done there, I can simply carry on again on the MacBook.
So there's ways around the limitations of the new MacBook, of that there's no doubt whatsoever. It would just be nice if Apple still catered to us as well and we didn't have to use these workarounds.
I'm sure I was going somewhere with this, but I forget, bloody morphine

so I'll just stop waffling now.
