Personally, I see a "convergence" coming with smartphones and cameras.
Smartphones definitely suffer from packaging limitations relative to cameras, but what of it? I have sold photos I took and processed completely with an iPhone (usually stiches of 6 to 20 captures). Sure, I can do a lot more with my DSLRs. But, I could do more still with my 4X5s, and that never kept me from buying the DSLRs. I don't shoot with flash very often, so that's not as big a deal for me as focal length choice, but everyone will have different needs. Though I still think almost any imaging device is useful for some photographic task or another.
But the computing power in the phone/tablet is highly useful as well. Most of them enjoy frequent OS and app updates that DSLRs will never be able to match. So why not use the camera for what it does best (capture), and the phone for wireless control, processing, and transmission? I'm already doing that with the iPhone app for my 6D. It's terrific. I can put the camera on a tripod in a corner where I can't physically go myself, and still have full control. Or even some little nook that is only large enough to hold the camera itself. As the phone/tablet tech improves, there will be more and more tasks that can be handled in the field, rather than waiting to get back to a PC.
I can imagine a really superb sensor mated to an exceptional lens, with no finder of any kind, designed to be used in conjunction with a phone or tablet exclusively. There are already a couple of Sony low-end versions out there now, and more coming from other manufacturers within the year. That might eventually end up being as big a trend as EVF cameras.
