Well, I'd say that in general, anything 'High Performance' is less reliable than its 'regular performance' counterpart. Will the HO EcoBoost (AKA EcoBeast) be as reliable as the 6.2? Probably not, simply because it has more moving parts... but would it be as reliable as the VooDoo V8 with its flat-plane crank and high-rpm power? Probably so! But no matter what, its always a risk with performance vehicles... the engineers try to get 105% out of them and sometimes they just go too far. That's what warranties are for.
I'm betting that even with all that stuff, its still quite a bit lighter... the turbo's and intercoolers don't add too much, and then 3.5L block is both aluminum, and a lot smaller than the 6.2, so I'd bet its lighter.
The technology in transmissions has taken HUGE leaps in the last few years due to MUCH faster TCU's and much higher hydraulic pressure in the trannies. Also, the old 6speed wasn't actually a 'new', the F-150 used the 6R80 transmission, which was based on the ZF 6HP26. That tranny was introduced in 2000 and was first used in the BMW 7-series!

The new 10speed transmission will benefit from more than 16 years of advancement in computer development, as well as recent advances in engine-transmission optimization. If you get a chance to drive a car with ZF's new 8Speed transmission in it, you'll be amazed at how FAST it shifts between gears and how smooth it is. If you bring this capability to something like the Raptor, the potential improvement in performance is mind-boggling!
I admit I don't know much about this issue, but a quick Google search tells me that its pretty common, so yes, I hope they fix it!
The body was never load-bearing on the F-150, so steel or aluminum, its not doing much to stiffen the chassis. The new aluminum body panels are likely stiffer (if only slightly) than the steel counterpart, but we'll never really know. You'd have to torque-test just the passenger-cell and no-one is going to do that! I will say that the crash-performance of the new truck is way better than the old one, so I bet they get additional stiffness as a side-benefit.
No matter the performance levels, the ecoboost are still having issues. On a truck where reliability is important, all the bells/whistles/mpg/extra power takes a back seat. Warranty and a tow won't help much if you break in Mexico or out in the middle of BFE. But, on the street or local dirt roads, the new motor should be a lot of fun. I like the ecoboost technology and it makes for a powerful package. I just don't believe it's the best route for the Raptor.
It will be lighter for sure, but quite a bit lighter I don't know.
The hardware wasn't the issue with the 6 speed. The programming was. Tune it and it shifts on demand. The new 10 speed may indeed be able to shift gear to gear quicker then the 6 speed. But if the programing makes it quick to up shift, hold over drives, and hesitate on down shift, all in the sake of fuel economy, how does it make it any more enjoyable then the out going 6 speed?
I meant the chassis being stiffer for the aluminum body so that NVH's didn't cause cracking or bonding issues. They went stiffer chassis on the 15s.

Won't you be sprouted when the new raptor frame is revealed and both shocks are mounted forward.... (I hope)
I agree. The IWE's will be toast!

I'm wondering if a key function of the terrain management system is to help keep the IWEs in one piece. For both the sand and snow modes, wheel spin and torque to the front wheels could be kept within limits by reducing engine torque and speed regardless of what the driver wants. It would be one way to keep from blowing up IWEs without actually fixing anything.
