I've read most of this thread, but not all, so sorry if this point had been made....but dSLRs is probably pretty close to a mature market by now. Not a growth market. And it is a market that is flooded with used bodies. A quick look at flickr and I am very impressed with how many old bodies are still in use. Top Canon body--5DII with an average of 3,711 members...next--T3i with 3,298 members. You don't get to a "current generation" body until the 5DIII at #6 with 2,144 members (granted the 60D, @#5, is barely no longer "current generation).
So while people on this forum love to talk about the latest gear and the next gear and what we'll be shooting with in 5 years. Most people taking actual pictures are using older gear not even current gear. http://www.flickr.com/cameras/canon/
BTW...the iPhone holds the top 3 spots overall:http://www.flickr.com/cameras/
I don't view that as a sign of the apocalypse, it is just reality. Camera phones have taken over the P&S market.
