If you expected new MLB commissioner Rob Manfred to either expand the DH rule to the National League or eliminate it, you can probably stop. Or at least put the thought on hold. Manfred appeared Tuesday evening on MLB Network Radio and addressed that issue (along with several others) …
Manfred on DH: Personally I’ve never had one moment of dissonance about the fact that the AL & NL play with 1 different rule. #MLB

You can catch the full audio at this link. Bud Selig also felt there was no need to make a change.
For the rule to expand there would probably have to be a big push from the Players Association — 15 more designated hitter jobs could be good for player income. That push has not happened yet.
And the DH is never going to be eliminated.
