I believe Shin is related to the Shinju(God Tree) with uchiha dna as well. He is most likely an experiment of Orochimaru. Shin has the potential to surpass madara & sasuke in his prime due to the fact he is very young and most likely have senju & uchiha dna.
The kid already has Mangekyo for godsake, I believe he's the youngest thus far, not to mention a S/T similar to obito's kamui. If my theory is correct and the current rate his visual prowess is progressing, he'll be the youngest uchiha in history with the rinnegan.
He could very well be a similar if not bigger threat than Madara. I believe thats why Naruto went RSM to comprehend his visual prowess/abilities, Naruto immediately grasped his mangekyo and S/T technique. Universal Comprehension FTW!
