Will nikon or Canon die if they don't go mirrorless. I don't believe so. Mirrorless is a cool new option not a huge new revolution.
The difference between film and digital was large, like the difference between standard deff tv and hd which is night and day. The difference between mirrorless and dslr is the difference between 720 and 1080 which is much less impressive
Based on the trends in the market (where mirrorless cameras are getting a an increasingly bigger share of what's left of the camera market), they have no choice but to jump into the mirrorless market.
Canon is technically already in the mirrorless market with the EOS-M, so they're already invested in the format. It was a piss-poor effort, but it did establish the format, and allowed them to get some lenses out the door. All they need to do is release a half-decent body that is comparable to a DSLR. They likely will when the market conditions are right. The dual pixel AF they developed for the 70D (in live view) is a natural fit for a mirrorless camera.
The rumor-mill very recently has also been hinting at a full frame mirrorless camera from Canon sometime in the near future.

But does a smaller lighter camera, which they're barley either, offset replacing or adding gear?

The only benefit really seen in mirrorless is size and weight. Take the Sony a3000 vs nikon d3200, two comparable cameras by specs, the a3000 is 128x91x85 compared to 125x96x77 for the nikon. That's beyond marginal. Weight is Sony 411g vs 505g nikon which is less difference than the weight of most adapters
The benefits go beyond size and weight
-More accurate AF, as it isn't hindered by the inherent calibration issues between the mirror and sensor
-Ability to leverage more accurate, yet very fast focusing, hybrid phase detect/contrast detect AF systems. (i.e. the dual pixel AF in the 70D via live view)
-Ability to AF across the entire sensor (contrast detect), and place AF points (phase detect & hybrid) across the entire sensor. AF and track motion across the entire frame vs in the center of the frame with DSLR cameras.
-Exposure preview via EVF, including ISO boosted image in view finder when shooting in low light
-More data within the viewfinder (focus peaking, levels, zebra patterns, histograms, grids, etc etc)
-Faster shutter speeds and FPS. There are mirrorless cameras that can shoot at a 1/16,000s shutter speed. Shutter speed and FPS is not limited by the physical movement of the mirror. its limited by how fast the shutter can open and close, and how fast the processor (and card) can write the data.
-allows for lenses with a smaller flange distance, leading to smaller designs
-no need for retrofocal designs for wide angle focal lengths. Any lens wider than about 40mm will benefit from smaller, simpler designs. This includes zooms that include wide angle focal lengths (17-40, 24-70, 28-135, etc etc)
-quieter (no mirrorslap). exception is the a7r, with its mechanic shutter
-less moving parts - most common component to break on a DSLR is the mirror.

For a lot of people, lugging around a smaller camera without sacrificing image quality is a huge value proposition.
For me as a wedding photographer, I lug the big hulking DSLR around for hours. There are merits to the DSLR right now as a work horse, but its not anything I like lugging around when shooting for fun. The size and weight savings don't look like a whole on paper, but in real world use, the savings are significant...particularly when using the typical 'walking lenses' as again, they can utilize simpler, smaller designs. The a7r also fits into a messenger bag that I take with me everyday, meaning I can reasonably have a high quality camera on hand at all times, and don't ever have to compromise. There are shots that I've taken because I had the a7r on hand, that I otherwise wouldn't have...and thats huge (pardon the pun).
I recently took the family to disneyworld...we make the trip often, and in the past, I had lugged DSLR's around. This time I brought my a7r, which I was able to wear on a spider holster all day. significantly less strain on my back after hours in the park, and much less bulky equipment to get in the way of enjoying myself and shooting for fun.
