Personally, everytime I open a copy of American Rifleman, Guns and Ammo, or any other popular firearms publication, I see pretty much the same thing on every page. I don't know what people expect... firearm manufacturers aren't exactly reinventing the wheel. Every product that gets introduced is more or less the same as something else already on the market. Not exactly surprising, companies have been ripping off designs from each other since the dawn of the industrial revolution and beyond. It will continue to happen invariably until technology produces something that does reinvent the firearms industry. Then of course, that technology will be copied packaged and reproduced by competitor companies the world over.
The Judge was something new, kinda, and the niche it filled was gimmick firearms, in my opinion. But pretty much every place I walk into can't keep them on the shelves. I'm all for new items, such as the Kel-tec bullpup shotgun, but people are fickle (to use the OPs term) because what is being advertised as new really isn't new at all. Yawn inducing rifles like the Ruger Scout are not new, but just a shuffling of features from pre-existing items.
But people being people, when the next revolution of firearms does come out, it will be met with disdain as well as excitement.
