>>33629353 axis stabilization is pretty good, even if only because it allows for proper sensor cleaning.
Seems like the body is a bit less wide and a tiny bit slimmer. The GR already fit perfectly fine in a pants pocket but a bit smaller is always nice.
Shame they got rid of the integrated flash. Didn't use the one on my GR (I) often, but it does come in handy every now and then.
Don't see why anyone would want a touch screen on a GR. It's a camera you use one-handed, and your thumb can only (awkwardly) reach half the screen. Buttons are love, buttons are life.
Disappointed but not surprised by the lack of weather sealing. C'mon Ricoh, just make it weather sealed and the GR would be the ultimate travel camera. (Would solve the dust issue as well)
