Hmm, you got me thinking so I did some digging. I just read an article and it sounds like you can skip gears.
Kept digging further and I found rumors that said they were 3.97, 2.32, 1.52, 1.15, .86, .67
I kinda like the new ratios if they are true. I would like a lower 1st and two O/D gears for better mileage at higher speeds. But the guys who want to dyno them are going to have even more issues. Our transmission has a 1:1 ratio in 3rd, looks like the newer one doesn't even have a 1:1 ratio. They say it jumps from 1.15 to the .86. And I guess to lower the shock of the shifts they are adding lower axle combos to go with it.
Here is where I found most of the information, its a pretty good article if you have time to read it.

Wow, its really looking like Bill has a lot on his plate for JUST the transmissions, not to mention they have 2 4.6s(I'm wondering how they souped up the high power one)
ones a 2v and the other is a 3v, the 5.4 and the 6+ liter engines.
I'm not sure how he's going to get all the shifting stratagies right on the new 6R140s because Ford is leaving all kinds of controls open to the driver. (probably so when something goes boom they can point the finger at the owner quicker)
No more od on off button. The button is now the tow/haul selector and it changes the tranny strategies.
On ours we can go in and pick where the truck shifts and locks with the 1st, 2nd and O/D. But now the driver can also make the stock truck skip every other gear or lock out the top O/D. I'm not sure how he'll be able to account for that.
