As we have seen that little monster thing can activate the same MS eye as Shin so Shin most likely has something similar to Kamui.
Would not be crazy if Kishi decided to bring in someone related to Obito. Space time techniques most probably run in Obito's family.
Theory: Shin and his father are from a long lost Uchiha clan, hence the almost similar Uchiha symbol on Shin's back. This clan most probably never went to konoha after the joining of Senju and Uchiha. Its possible that not every Uchiha sided with the senju and decided to live in Konoha. Obito's parents were probably from this clan.
