I think it's good for no other reasons other than to get the game into the hands of people who haven't played it.
As the years continue, games on DS and 3DS will become increasingly difficult to play due to their unique form factor, and getting ahead of it and bringing as many games over to systems with a more traditional controlayout can only be a good thing I think.
I think that's a reasonably take.
Alternatively, they could just be implying the joint universe without actually doing anything with the Bandai-Namco IP.
They could just avoid using Kos-mos, etc, and that would be fine enough to avoid conflicts.
Or they're only paying for it for a single game perhaps?
