I'll make a prediction.

Within 3 years, all of the big three, and perhaps the Pacific Rim trucks too, with be mostly aluminum. Starting in 2016, most will have composite beds as an intermittent stop-gap until tooling catches up.

All one has to do is look at the CAFE standards, especially the one on light trucks, to know things will be getting lighter, if not smaller as well. Progress don't you know?

I think your wrong. Aluminum has its problems in crash and repair, It seems Ford knew back in 2012 that regular cab and super cab would fail crash test but decided not to fix it at that time and focus on crew cab model were weight savings are less that advertised because of steel reinforcements. (advertisement is for non reinforced models) When you reinforce cab with steel for crashes weight savings are less and repairs cost more because of hybrid structure and aluminum in general. The answer lies is strong light weight steel and some aluminum body panels. The also need to change engine design and move to Atkinson cycle motors and stop the HP turbo wars. While turbo charges gas motors make more HP per pound they use more fuel per HP produced and at high boost it uses even more. The main reason that Prius gets such good MPG is its motor which runs on a Aktinson cycle which is more efficient than otto cycle. Trade off is less HP per cubic inch and high RPM performance. A Atkinson cycle motor is so efficient that it makes little exhaust noise as mixture is fully expanded when valve opens. By using very high compression ratios (13 to 1 and higher) with different valve timing so more energy is captured. Current Prius motor is said to be over 40% efficient now vs 30% for average gas motor. Advanced hybrid designs and Atkinson cycle motors are key to future MPG not aluminum truck bodies which is a banaid at best. Diesels are no magic solution either as they are BIG NOx generators by default and to make them more eco friendly they loose some MPG and require ammonia injection too.
