I asked this a few weeks ago, but I'm sorry, it REALLY seems like the New Earth continuity is back as the mainstream DC Universe. Still haven't read Death Metal or Infinite Frontier, so maybe I'm missing something, but unless someone can prove me wrong, I really feel like we should go back to the New Earth pages for our mainstream universe. I'm thinking maybe we add information about the Prime Earth stuff that's now New Earth canon (for example, Tom Taylor's Suicide Squad and parts of the Rebirth Squad run have been confirmed as canon now alongside the original Ostrander run). The headers for "Mainstream Universe" on infoboxes need to be changed, too. Prime Earth's now has to say "Mainstream Universe, 2011 - 2021", while New Earth's should either say "Mainstream Universe, 1986 - 2011; 2021 - present", or just "Mainstream Universe, 1986 - present" (I prefer the latter, myself).
Again, please correct me if I'm wrong here.
