Martin probably did not study the issue because he did not live in the end times we find ourselves in. He was antisemitic when he died.
Luther was concerned with other issues, no doubt, like indulgences, and translating the New Testament, and avoiding being killed by Leo X. Therefore, it seems that what he did not deal with, he was not called to deal with, and did not. I did not know if he had a position on prophecy or not, and it does not seem like he did, save for leaving that part of Catholicism alone.
It does seem like things are progressing pretty fast, though, as I said, I am Reformed, and tend toward semi-preterism. Prophecies can be fulfilled more than once.
