Beit Shammai in the Future

Question: I have heard that in the times of the Messiah, the Halachah will not follow Beit Hillel as we do now (Berachot 36b, Beitza 11b and Yevamot 9a), but it will follow Beit Shammai. Why?
Answer: This idea is written in the works of the later Kabbalists, but it does not appear in the Gemara or in the Zohar. Nonetheless, we must understand that Beit Shammai discusses the world in the future in which our world will have a reality more appropriate to the stringent positions of Beit Shammai. Beit Hillel intended positions more compatible to our current world.
