I like the idea of it, apparently based off the Colorado ZR2 which imho, is a good thing. But if it really does happen, what kind of focked up world will that be? A Blazer is a little tiny Cute Ute and the Jimmy is real off-road type rig? No sir, I don't like that part of it. They are supposed to be a pair.
As capable as it would be, I don't see it as a competitor to the Wrangler. The Wrangler is solid axles and has one hell of an aftermarket to support them. Many people buy Wranglers with the specific intent to modify them, and even the ones that don't, probably dream about doing so. But the Jimmy would be IFS and lift kits are going to be much more complicated, expensive and also less kits to choose from. For that reason, most people won't modify them or even have the desire to modify them. If people tend not to modify them, there won't be much aftermarket support because the buyers simply won't be there.
