iMan, the question you should ask yourself is where is the market headed, not where it's been. To give you an idea, I firmly believe that cams are the early stages of virtual reality which will peak in a few more decades, people say that the resolution is shit, or how do I use those blurry pics for a FS or gallery, but times are changing fast, and we are just getting warmed up.
The people who made it big, alot of times were in the early stages of a trend, or helped to pioneer that trend themselves. But alas, all good things must come to an end, and porn mediums are no different. Change, adapt, and evolve to suit your surroundings, don't be obsessed with an idea so much that you lose perspective and you may just make a few bucks in this biz.
Good luck
