While I won't disagree that there is no replacement for displacement, I know there are people like me who live at high altitude who are are happy for a turbo option.
I live at 7,000 ft and tow up to 10,000 ft often. Assuming 3.5% loss/1000 ft, the 411 HP 6.2L is down to just over 300 HP at 7,000 ft and sucking wind at 10,000 ft to the tune of 260-270 HP.
A turbo engine does lose some power at higher altitude, but it is a much smaller percentage. At up to 10,000 ft an ecoboost is still probably putting out 90% of its power.
Also, if towing at altitude you are supposed to reduce the tow rating of the truck. An F150 won't tow 10,000 lb at 8,000 ft (well, it will move it, but not very well). My dealer typically tells me to reduce tow weight by 4% for every 1000 ft of altitude, so a 10,000 lb rating is down to just over 7,000 lb, and it gets worse the higher you get.
Yeah, I could buy a 3/4 ton turbo diesel, but I don't have $50K, and I don't need to tow 15,000 lb.
I know I am in the minority, but there are people like me who deal with our normally-aspirated engines sucking wind everyday and welcome a change!

The EcoBoost motor runs COOLER with direct fuel injection cooling the heads....also the Honeywell turbo is the first on the market with water cooled bearings that extend longevity to 150,000+ miles with no coking, (gunk build up for you simpletons) on the bearings from burnt oil in Ford's on durability testing WITHOUT ANY PROBLEMS....this thing has been tested and retested and is not new technology.

Knowing Ford they will charge a 3K premium (like the 6.2)for the EB and some people will buy into the MPG/power hype. Then buy it and realize that you just paid that much for maybe a 1-2MPG increase. And, since the F-150 is so heavy, you are gonna be relying on that turbo quite a bit, minimizing the claimed gains in fuel economy. For my money I stick with a V-8, or how about a light duty diesel? Now there is an idea. Actual fuel savings, increased durabilty, and increased torque. All the things Ford claims the EB is, but with the diesel they are actually true.

To prove how durable, tough and powerful the all-new 3.5-liter EcoBoost V-6 can be in a half-ton truck, Ford plans to torture it later this year in a Raptor R off-road race truck, according to our sources.

Recently, our spies took photos of an EcoBoost-equipped 2011 Ford F-150 FX4 half-ton pickup racking up test miles in the desert, but that’s child’s play compared with the grueling conditions the engine will face powering the Raptor R.
