Probably because they'll come out w/ a half-cab top like they did for the TJ and charge alot more for that setup, even though it's basically the same thing.

 

I figured they would. The three piece setup is so much easier. But, you do need to get the door rails for between the safari and doors so it completely seals. BTW, does anyone know the part # for this. I saw it on another thread ad 55395763AC for the 4-door. I ask 3 dealers about this part and that # doesn't come up for them. I need these rails!!
