Probably will be stolen just to recycle the all aluminum frame.
But... I am in need to update my 4 wheel device and I am interested in the new 2015 Colorado, later on they will offer an inline 4 cylinder Duramax for it.
I just bought a very nice low miles 2012 Equinox 2.4 AWD just before Thanksgiving and I really love it, the Colorado is supposed to be priced about the same, far far less than the estimated $55,000 I may have to spend to get a loaded Silverado HD in the 3500 series, of course the Colorado is much smaller than the 3500 but then my 2002 3500 dually is still problem free at over 100,000 miles.
The frame is still steel.
Aluminum Revolution: Ford introduces a new F-150
http://fuelfix.com/blog/2014/01/13/aluminum-revolution-ford-introduces-a-new-f-150/
Ninety-seven percent of the body of the 2015 F-150 is aluminum...
Some steel remains on the truck. The frame beneath it is built primarily of high-strength steel, which Ford says will make it tougher and stiffer than the current frame. There’s also steel in the front dashboard, because Ford thought steel was better at dampening nose from the engine.
