Is mirrorless camera the future of dslr evolution?

I'm shocked to find it so late: P
my friend used Olympus OMde5, and i quickly get curious, as i know he is a Nikon guy professionally.
first Olympus uses smaller sensor, a four thirds sensor, and the images seems to be brilliant.
then i start to notice youtube reviews saying this is where the next camera form is going.

i'm aiming to be at the pro camera gear. So i have a dslr and all full frame lenses.
but Canon make new mirrorless too, and it can use EF full frame lenses.
i wonder if its worth adding more EF collection or soon everything going to be turned into smaller lenses like Olympus zuikos and Sony zeisses. They produce amazing result and have incredible opening at f1.4.
Trey speak about it with people at google hangout about it too.

i'm just worry that if i keep upgrading Dslr, my items wouldnt be worth it soon,
should i be prepared that pro photographer gear will also be in the mirrorless world.
will all my lens will be replaced by smaller L lenses options?

There's a lot of pressure to create a camera between a dSLR and P&S camera.

The mirrorless camera is what has evolved.

Pros will still need the flexibility of a large sensor, fully adjustable dSLR's and interchangeable lenses.

Those of us who use long lenses, need the extra mass of a camera like a Nikon D4.

Well, it's pretty much the norm for point and shoots already. I suspect that when mirrorless DSLRs do things that mirrored ones can't, then the market form them will expand. Other than high frame per second speeds (which most photographers never need), they don't do anything better than a mirrored DSLR does already other than display menu information through the viewfinder. But once you know how to operate your camera, that means nothing. As for the Sony Zeiss lens, the Zeiss is name only. There's nothing German about them other than name because those lenses are made in China just like all of the other point and shoot lenses.

Rather than being afraid you're not going to be on the cutting edge of technology, it sounds like you have decent equipment already. As long as it serves your purpose, forget blowing a bunch of money on something that may or may not be a fad.

With the cost of full frame DSLRs starting to go down, in another generation or two (of camera models), we may see a $1, 000 full frame DSLR. If/when that happens, cropped/entry-level DSLRs may very well lose ground to mirrorless cameras.

So I see one day that all DSLRs will be full frame, and mirrorless cameras will fill the gap between DSLRs and Compacts.

I really hope not.

The SLR is as old as photography, coming to prominence after WW2 as some of its more annoying eccentricities were worked around.

The ability to see the final image has been the greatest single leap in the history of photography, and no electronic viewfinder, however sophisticated, can replace that.

The mirrorless camera is only an offshoot of the dSLR camera. It was not meant to replace the dSLR.

Why worry? Why even upgrade? Buy cameras and lenses and use them to shoot pictures. Don't keep track of how much would they cost a couple of years down the line. It takes the fun out of it. What format you decide to go into doesn't matter. It's how you use your equipment. Medium format, full frame, crop sensor, four-thirds and micro four-thirds are all just specs. What matters is how you make good use of what you have and get the best pictures you can produce. At least that's how I go about it.
