Wait a few days and it will be 2009!!
Back to your original questions.
Making the transition from 2D to 3D is surprisingly easy, with all the benefits for you as a designer, your clients visuals and the team making the furniture.
I have always produced 3D visuals, since starting with MiniCad, adding them to the standard shop and working drawings.
On the design front 3D resoulution comes very quickly.
Also with a 3D model you then have all the elevations, plans and sections you need as all the VPs are dynamic.
You can create templates for different styles of projects, including VPs, Worksheets, etc and
We're thinking Architect mostly for the productivity tools. Chief among these is batch printing and pdf output. Til now it's been print to pdf one (design) layer at a time, and a third party app to combine into one doc.
You can even build the batch printing into the template.
