2015 likely 10speed trans

Like Dodges ZF 8 speed it'll skip gears most likely. Only using some gears for sweet spot downshifts or using more gears during towing. Main thing is you can run a 3.08 or less gear with a 10 speed and have the same take off power as a 4.10 with the 4speed 4r75. Then great highway mpg.

Just because it has more gears, does not mean that is always good. If you tow, that 8 or 10 speed with a 3.08 will still end up dead due to excessive shifting, not at starting out, but w2hile trying to stay at a highway speed. That will kill it every time. That extra MPG will only happen in the city as the top OD gear will still be about the same as the current 4 or 6 speed trannie. Can't go any lower without making that transmission constantly shift to hold highway speed.

No if you run a ford typical 3.55 or 3.73 running a 3.08 will be a big rpm drop for freeway mpg. Loosing 700lbs will also help the drivetrain even in towing. So instead of kicking from 4th into 3rd gear the truck will go from 10th to 7th gear. It may only use 7th gear only when towing up hills. It may skip it all other times. Who knows maybe 7th gear from 10th at 70mph puts the truck exactly at 2800rpm where peak torque of the engine could be making it effortless for the truck and you dont notice anything but an rpm change.

Are you surprised? You shouldn't be. Ford worked together with GM on some 6 speeds...

Yes they do but 99.9% of them are manual. Fleet owners will not spring for the extra cost of an Allison auto and 99 out of 100 owner operators won't either. Most, if they have the coin to spend would rather have the big horse engines than spend the 30K plus for an allison. And last I heard the allison autos only had 5 speeds anyway.

10 speed transmission is inviting failures with any sort of load. It's like Ford is finally realizing most F-150 owners are just driving to the grocery store and back and building them like an Escort or Tempo...

CVT isnt in the conversation, so why bring it up? I dont think they will ever be able to produce a CVT that is capable of functioning reliably on a truck.
