I myself had a very bad experience with the knockoffs. The 3l pins are the most fragile things in the set. Pull it wrong and you have it broken.
Some pins actully MELTED and fused with the rubber hoses.
Judging from the licenses tlc got from Ford, Chevrolet, Audi, McLaren and Mercedes makes a possibility for future Technic ultimate sets to be one of them.
This is considering the licenses obtained for the speed champions series
I also noticed the book has many pages with darker prints and light background.
What I meant to say is that the pages are not in the standard blue like all the other sets but of a different shade and also with a lot of extra info.
Without all the extra stuff the size of the booklet must be close to that of the arocs
With what I see, it might be a bit of a challenge to incorporate those orange fender panels since there might not be enough beams in the same colour for that car.
But the good thing here is that TLG already bought some other parts in orange for the previous sets .
hence bricklinking parts in orange wont be that costly
p.s. all this is assuming that TLG uses the same shade of orange in the Porsche.
