Yes and no. The EB gets its best HP/torque using premium, not regular, although it will run on regular. The 5.0 numbers are with regular. That kills at least part of the mileage advantage. How much is still to be determined as the official (EPA) numbers are not out.
Other things I question as others have is the durability, especially of an engine that has been "tweeked" that much. Hope it is good, but only time will tell. That also holds true of the 3.7 and 5.0, but not as much as they have not been tweeked like the EB. Another question will be what happens with the 3.7, 5.0, and 3.5EB as compared to the 6.2, as they are all aluminum blocks, while the 6.2 is cast iron. What will happen on a bad overheat? Aluminum blocks do have more problems when overheated.
I sincerely hope all will be good, but most of these changes are for one thing and one thing only. New mileage standards.

Do some research before you argue a point as the gospel.

Ford's "Best Performance on Premium Capable on Regular Unleaded" quote simply means the engine will make more power on premium fuel. The 365/420 number is regular unleaded.
I asked the same question in another thread and was quickly reminded that the power numbers are based on regular unleaded. The proof was provided there so I'm not going to search for a link...

Have done a search and nothing I have seen states premium or regular. And since when has any auto manufacturer advertised the lower numbers om HP and torque. Ford who put up the best numbers for the engine, which would be the premium numbers. If you have any sites which state the fuel type put them up. I asked the same question before and got no response.

Its been cyrstal clear: REGULAR

Here you go, taken from this thread.
I did find an interesting tidbit in my search. These things have a fuel pressure of 2150psi. imagine working on it and have a fuel line go.

Thanks. Interesting that they wouldn't advertise the higher HP/torque of premium. Something you do not normally get with a NA engine.

The high fuel pressure is the design of a Direct Injection motor. Diesel motors have similar, high PSI at the fuel rail. Most Direct Injected motors have 2 fuel pumps. One at the Fuel rail in addition to the In tank pump. You can look at Mazda's 2.3 Turbo motor or Audi's 2.0 FSI motor for reference.

I've done that. Still no squeaking of tires 
Here's thread I started to try and not derail this one
https://www.f150online.com/forums/20...nse-power.html
Somethings definitely not right there, I accidentally chirp my tires all the time and I'm not even hard on the throttle. If I actually floor it it'll spin them pretty good for a little bit. Gettin loose at 45 is out of the question though haha, that'd be pretty impressive to see from a stock f150!

EB, all the way...
The biggest problem that FoMoCo is going to have overcoming the opinions from the core truck population is that a V6 can't do the job of a V8... quite the contrary.... towing a 8k+ trailer with the EB was a breeze and it had plenty of oomph to get up and over hills -- past semis -- and plenty of power to accelerate. I was *VERY* impressed with this motor!!!

I would love to trade my truck in for the EB. I am not concerned with the workload because I am sure that Ford has taken that into account before producing this motor and chasis combo. Iam more concerned about the sound....I love my V8 rumble. Would be funny to put a big BOV on the EB though
