A more general answer, I feel like the web programming world doesn't really need new frameworks, does it? Rails or Django got mainstream adoption because there was a need at the time, likewise with frontend JS frameworks (which seems to be consolidating around just 2 - React and Angular), and likewise with Node as filling a need for easy async. I'm not that knowledgeable on Meteor [1], however I think by default it's reasonable to expect no new frameworks to have mainstream adoption without a major change to the web.
[1] I don't know if Meteor's x-platform appeal is enough to convert users from other x-platform, native and/or hybrid solutions (Ionic, Titanium, RubyMotion, etc.).
