I voted Earth 1 as well but dont think that'll be happening. Best of both (all?) worlds that DC will probably try to reconcile ALL with a major film coming out is a combo of Earth1, Birthright and inital 86 reboot (no Superboy). A more self assured, confident, morally fit Superman with ideals and integrity and not this dark buffoon who's been running around in a cape. Maybe
that Superman shoulda stayed dead!
'No Superboy' would tie in with Smallville but once SuperMAN announces his presence in THAT world, how long do you think it would take for the Smallville town fathers to take down that Meteor Capital of the World billboard and replace it with a Home of SuperBOY one. Somebody's gonna finally put all those miraculous feats together and make sense out of senselessness.
Vince Sullivan's namesake perhaps?
