When there will be Major League Baseball again is anybody's guess. When the games do resume I expect one change to become permanent: the universal designated hitter. I used to be an NL purist. The DH was "an abomination" in my world. That world started in 1973! It was the summer--for me--between elementary school and high school. I'm 60 years old and will be 61 in November. I was 13-going-on-14 in 1973. That's a long time to hold a grudge!
Actually I had become indifferent to the DH issue some time around the new millenium. I'd watched enough post-season baseball in AL parks and seen enough live baseball (amateur and minors) to stop caring.
