DDJ-RZX vs Full NXS2 setup for RekordBox Video

Hello,

This maybe a question for an administrator: I'm trying to make a purchase decision  and I am wondering what video controlling functionality is available on the RZX that is not available on a full NXS2 setup. I see the screens on the RZX and I see the ability to control when and how to fade from the controller. Will a NXS2 mixer + 2000NXS2 combo give me the same capability?

Thanks
