Maybe everyone eventually, but for me, soon. I'm jumping ship and moving on to a mirrorless system, the Sony NEX-6. Right now I still have my D300 though it's listed on CL. I'm keeping the glass for now since I can use it on the NEX with an adapter. I'm hoping a smaller system will get me back out shooting again since I've been really hating lugging around that brick of a camera body that is the Nikon D300. Anyways, I look forward to posting up some shots from my new camera when I get it...maybe end of this week, beginning of next.
You think everyone will move on to mirrorless cameras? Yeah it's called a smartphone. My Iphone is my point and shoot. I love my brick DSLR its not going anywhere.
