I suspect changes are going to be limited to just fixing the "issues/problems" that they have discovered in the first year of manufacturing. They may make some minor tweaks and add a tad more content, but I suspect changes will be extremely minor.
There are however a few things I would like, but I have no idea if they will happen.
1- some better color selections, the options now are for the most part all too dark. (I'm going to start a color thread I think to explain in detail.)
2- expand the number of ways you can equip the truck as in break down the option packages into smaller bundles. EXAMPLE- let me have a sunroof in a KingCab, don't restrict it to CrewCabs only. Let me have the side fender storage compartment without all the bedliner, track system, tail gate lights and power outlet in the bed.
