I think there might be a bubble in the DSLR market.
As DSLRs are being made more cheaply, more people are getting out of P&S and upgrading to DSLR. Right now DSLRs are still considered cool because it has the "being more professional" stigma attached to it, and soccer Moms and Dads are very happy to grab one for Christmas, for both an upgrade in image quality and obtaining the "cool" status. Out of the large number of people upgrading to DSLR, actually very few people are interested in photography, or will have a long term interest in photography.
Overtime, everybody's grandma will have a DSLR (looks like it's getting there), and owning a DSLR will no longer be considered cool. Most of the P&S shooters who upgraded will realize they no longer need a DSLR as P&S image quality continues to improve while they get tired of the larger size of DSLRs. At that time, a simple P&S marketing tag line as "DSLR image quality in a small package" will cause a mass exodus over time in the DSLR market.
At that time, our local craigslist will be flooded with Rebel T1i, T2i, and etc.
