Those features have been there since the early 90s, and my uncle's 1992 Silverado (a work truck, BTW) has them all.I fail to see how the availability of certain features proves their use as personal transportation...but whatever I'll engage in a suspension of disbelief for a minute.
SUVs are widely used as personal transportation. Pickup trucks are...but to a much lesser degree since they are not as flexible as SUVs.
I really would like to know why you think RWD trucks have been the selling point when the sales trends have indicated a preference toward AWD, especially for those using them as personal transportation. People in the snow belt have turned to AWD (up until recently only available on trucks and SUVs) for its superior snow handling.
Really, the only trucks that I have seen with a large personal transportation (versus strictly work) use are the Avalanche and Escalade EXT because they provide the flexibility for cargo and passengers. Unless you buy crew cab, a pickup isn't that passenger-friendly, and even then, less so than a comparable SUV.
Again, I don't think the Zetas will steal sales from F-150, Silverado/Sierra, Ram, etc...they will steal sales away from Avalon, 300©, Charger/Magnum, Crown Victoria/Grand Marquis, Maxima, and the other similar cars in the same size classes. Wouldn't you rather them do that, anyways? Trucks are a stronghold of the Big 2.5, and I would never advocate internal sales cannibalization. I'd rather the sales be taking heat off of the foreign competition, and I think they will. If anything takes the heat off of trucks, it will be crossover SUVs and other similar vehicles that offer comparable features to trucks: AWD, command seating, cargo flexibility, V8, etc...I just don't see very many people forsaking the open truck bed and command seating for the enclosed trunk and butt to the floor seating just because of RWD and V8. I really don't.
Let's just wait and see what happens when the Zetas come to market...then we will see who is more and less correct.
