from this news story:

The new versions of these characters in Earth Two have all been aged down considerably, to the point that Scott’s gay superhero son Obsidian had to be sacrificed. Robinson says he was inspired to write Scott himself as a gay character to make up for that loss. “The logical leap that I made was, oh, why don’t we make Alan Scott gay?,” he says.

dc has pre-announced that if sales on the book are strong, “in 2013 all our characters will have always been gay”

i stopped reading comics because all the continuity reboots and shifts and changes will all get put back if this doesn’t work out, there’s no consequence
