Yes and no.
Basically, it's a simple reality that people are more likely (right now) to save that budget excess whereas 6 months ago they'd more likely spend it. People are spending less across the board, and times like these are when you'll see cutbacks in areas that are for hobbies or maybe even just done on the side. I've felt that there is an obvious slowdown when it comes to domain resellers and flippers. (The category of people that you'd find at places like here at Namepros.)
The other side of the coin is that the internet offers (and domains by extension and necessity of use) a place where a business can start with minimal costs. For this reason, domains dealing with end users will probably continue to do okay. When someone needs that domain, they need that domain. For example, things are tighter for me, but I just picked up an end-user domain for my future in-laws for their local business.
