Welcome, Tregard!Having anal-retentively documented Roadblocks and, as a result, Fast Forwards for several seasons now, I feel in a position to sort-of answer this question. I made note of when Fast Forwards have appeared in previous seasons in my Roadblock Tally thread (scroll to the bottom of the linked post).
Also, you'll see there that in Seasons 10 and 12, there was only one FF. It's possible that they just weren't shown, like the FF on Leg 7 of the current season, which is also discussed in the Tally thread (Check out BlueIris's Post #21).
So all of this to say if there's going to be another FF, it'll probably be this week.
I never kept track of U-Turns, so I don't know about that. It does seem unlikely that there would be both a U-Turn and an FF in the same leg, and a Superleg at that. Possibly there already was one, and no-one chose to use it. Which also seems unlikely.
Hopefully this wasn't too confusing. I drank coffee with caffeine in it earlier instead of my usual decaf and now I'm all jittery. *shaky smile*
