i agree that crop frame SLR cameras days are numbered. Not in the next couple years or anything, but surely they won't make it out of this decade. Death from FF slr's, mirrorless things, or something else will take them out. Sure most people don't know the difference, they use their camera phones. But when then go online or walk into a camera shop they will be told about the differences. sensor prices will continue to fall, hence ff camera body prices. the lens lineup with consolidate, new ef-s lenses will stop being designed. they will likely be MADE for a good while after new designs have halted, and repairs will continue for a good while after that happens. but the day will come when they are no more. Are crop frame bodies , with lenses attached considerably smaller than FF stuff to justify their existence on size alone? Compared to mirrorless offerrings? Can someone name something electronic that hasn't gotten faster, smaller, cheaper, and better for less? that's a real question, perhaps there are examples, i just can't think of any. DSLR's are computers in highend cases.
