As I’m under NDA I cannot tell you much but I’ve put together some of the public information if you are curious on what the next AutoCAD release holds.
One thing you can expect is better PDF output. Interesting to read that according to Shaan’s tests the AutoCAD 2009 Bonus Pack 2 makes smaller PDF files than AcroPlot and Adobe Acrobat Pro 9. If I find the time I will do some tests myself and look forward to read about others testing this.
