I'm certainly waiting for one as a photographer who loves shooting birds the most. A crop with a 2014-era sensor and lots of pixel density is what I'm waiting for. No 2009-era crop sensor for me . . . I already have that and the iso issue is my biggest challenge every day.
Yep . . . I'm ready to "pull the trigger" when it finally comes out. I'm sure there are a lot of others who are too.
