Someone might have already mentioned this (with such a big thread)... but if you look at one of the Hi-Res pics, there appears to be a slight indention/cut-out in the lower right hand corner of the rear LCD. I 2nd what people are saying about the Touchscreen. After the GRiii, its a logical progression.
I find the 4th scroll-wheel in the middle section interesting. It has Camera/LV/Video, so that unlabeled button the back might not be for LV. The fact that LV has its own function/setting is kind of intriguing. Seems like prime real-estate for something that is so minor. The wheel is also occupying where the 3rd-scroll wheel selector would be (on KP/K-1), so how exactly would/do you select options for 3rd wheel? I also hope that the Joystick means a big bump in # of AF points, because I really don't feel like I would need a joystick for the small amount of points that we currently have. Aside from the unlabeled button on the back, I wonder what that button is between the ISO/exposure comp buttons. It says S?.Fn?? Maybe it interacts with the top-LCD somehow? There is definitely no shortage of buttons and dials on there!
It's pretty standard for it to have a Mic/Headphone jack now, but be nice to have features to justify it. That SD-card door looks mighty small for 2-card slots.
