Well actually dodge uses the cummins engine. Cummins is its own company. Its basically an automotive version of their ISB engine you would normally see in straight trucks. They aren't loyal to dodge, dodge just uses it instead of designing their own diesel. So nissan may very well be just taking the same approach as dodge and using that option. Though you may also be right, i suppose we'll have to wait and see! Interesting idea though, I'm anxious to see it now
