While I would love a supercharger, it's not going to come standard.. ever... even on a TRD Pro model.
Leaving that item an option, will bring the price down substantial enough that the (already limited) market will support more sales of the "special" truck.
By leaving the supercharger an option item, they can also more easily put it in the accessory catalog. i.e. wife will shut down dad shopping for a race truck, but will roll over for a catalog that also includes a tissue holder and where dad can say the extra power is to tow the camper/boat.
Just like Volvo, Honda, and virtually all other auto makers, the "performance" line will be more stickers and trim bits than actual performance.
The suspension is an easy swap and that will happen. I can also see TRD rims being standard, and the TRD intake.
