I think it will be much like the T|X Baja and FJ TT packages for the Tacoma. You'll see wheels, exhaust, remote reservoir shocks, and a little more sinister of a look.
My uncle has the Tacoma T|X Baja. The suspension is really, really well sorted. It drives great on and off road. If you are the type that wants to stick OEM and doesn't mind paying a little more up front, it is a great option. Honestly, if a Baja-esque suspension and some nice little touches here and there is what it turns out to be, that is what I'd opt for if I were buying a new 4Runner. I simply don't have the time or energy to fiddle with aftermarket suspensions or blacking out things with plastidip. I left my SR5 stock except for tires and mud guards for the 4 years I owned it.
