I don't really believe when websites says the region of the blu-ray anyway! For example, Amazon US says the A League Of Their Own blu ray is region 1, but in reality, it is region free... https://www.amazon.com/gp/aw/d/B00KRQ4M6U/ref=mp_s_a_1_4_twi_blu_2?ie=UTF8&qid=1503043020&sr=8-4&keywords=a+league+of+their+own It happens with a lot of blu ray! We will know for sure when the blu ray is out!
Edit: My bad, when I'm on my phone, it says Region 1, but on the computer it says All regions ! Don't know why...
