Did DP let this slip prematurely?
EDIT: I see it's offcial.
It may be a somewhat smaller upgrade from the G3 but I will be going from a G1 so it looks like a win win situation for me, especially as the G5 seems to be taking some cues from the G1 with the new design (bigger grip, eye sensor etc).
It's a shame they didn't include wi-fi and the build materials seem a bit skimpy but we'll see what the final review says with respect to that.
My only criticism of the G1 was that the buttons on the back were too small and the labels wore down with use.
I'm looking forward to this camera.
