Interesting changes, I wonder if these new pans are easier to get on and off. Not that the current ones are hard but I do find SOMETIMES I have to fiddle a little bit to get it to find it's home. I think I liked the rolled bottom on the pan itself.
As far as them ever doing away with the open ash pan model, I highly doubt it. Just going on what I see in the apartment complex I live in (which is a sample size of 1,000 - 1,300 apartments) I'd say EASILY three quarters of all the Webers I see here are the open ash pan ones. The other 25% is almost entirely Golds, I think I've seen maybe 1 performer.
