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.
I'm about to pull the trigger to go mirrorless too...in the next couple of weeks I'll be picking up an Olympus OM-D...
