The pressure is coming, but at least from where I sit.....nothing touches my DSLR. I see the appeal for the hobby shooters and enthusiasts.....in form factor alone its great for carrying. I am coming at it from a working pro though, I don't see a family of cameras even remotely close to my DSLRs in versatility, image quality, durability, usability, and reliability.
I have large hands, and routinely shoot for 8-12 hours during some days. I've held the Fuji cameras, my hand would struggle with them all day (same as they did on a consumer dslr). Yes my bag of lenses and cameras is big, and heavy, but its that way because they are made out of metal and glass, and are fast lenses. They get beat around 300 days out of the year, and perform admirably. Dirt, moisture, wind, salt, you name it they have been through it. Personally the large format I think gives you better access to your buttons and functions to run it without looking, and I still say holding the camera to your eye is the best way to compose a shot.
I get the appeal, I've considered a fuji for personal use and trips, I think it would be great for that, I just don't see it for the all day every day grind yet, but then again others may disagree and thats ok too.
