Another sign is the cutback in travel. CAD vendors aren't flying in the media to wine and dine them and to demo the soon-to-be-released software in person.
The cheaper, almost-the-same alternative is the WebEx demo. WebEx and GoToMeeting events certainly do save time and travel money -- and are just as effective as sitting in person in a CAD vendor's conference room several timezones away. But WebEx still costs money to host.
And to save even more money, several "online" meetings I've had recently were telephone-only. If there are visuals, they consist of a PDF or PPT file emailed in advance.
Just some observations.
