I agree completely with Djordje. Archicad is - and has been from the start - all about productivity and ease of use. It's not primarlily a free-form modeler for Gehry-type stuff. However if you want to do that in AC for some reason, there are options and add-ons available, as well as import options from other modelers.
But productivity, easing the architect's burden of getting paper and digital documentation for the producing of buildings out of the door, that's the core of Archicad. The bulk of these buildings don't use slanted walls to such an extent as to motivate a priority development. They are special, and need special tools.
AC9 adds a list of productivity enhancements, some of which have been on the wish list for several years, along with some lesser. I'm very happy the new management at Graphisoft now is listening to the users in a way they didn't do before. It encourages me to think that they will eventually run down the list to what oreopoulos wants as well.
To me, as a maybe less high-aiming architect, I still have things on the wish list with higher priority. I'd like to be able to open several different 3D windows at once, and I'd like them all to be simultaneously updated in real time, to see what I'm doing when I work. I'd like to be able to add text and 2D symbols, as well as shadows and shading, in all windows alike, wether plan, section or 3D. I want to get rid of all modal dialogs - I want to be able to have any I like on-screen, with an Apply button to use if I want to change a setting.
These are all productivity enhancements, no new modeling tools. Still I'd be happy to call it AC10, because it would change my way of working. It would make me faster, and perhaps give me more time to think about slanted walls
