They'll sell a ton of those bows....based on the camo pattern, alone (it's just true). It's bad-ass (the predator)....and it's a smart move that will likely pay off.
I can only guess ($$) why the "more" mainstream bow companies haven't tried to land (or....the other way around) the newer, open-pattern camos for their bows. It's a trend I'm not sure we'll see more of any time soon, though (unless the camo companies relax their licensing requirements and make it more palatable, financially, for the mfr's).
Teaming up and getting this pattern on a new line is a win-win for both companies.....especially if there's an exclusivisity agreement between them.
