They're horrible, and not improving. DSLRs are "out there" already. Sales should have plateaued. Sales should only be to existing owners upgrading, and a few new entrants. If mirrorless cameras are the next best thing, they should be dominating as all the dSLR owners buy into the system, and there should be more upgraders from other areas because they are so much better.It sounds like sales numbers are pretty good and getting better all the time.What about it?You might want to take a look at this:None of the current systems are very interesting, as evidenced by their low sales numbers (all systems combined sell around half as much as just Canon's dSLRs). The Nikons have an interesting feature - on-sensor phase-detection autofocus, but even that doesn't seem to have attracted much of a following. So what can Canon do to such a system to make it interesting to either compact-camera buyers (largely people looking for an under $350 camera to put in a pocket or purse) or dSLR buyers (people looking for much better performance than you can get from a compact)? I've got nothing.

That's not happening. Canon is planning on a 30% increase in dSLR sales this year.
