Well, you have this all figured out then....except people don't speculate on comics because of story anymore, it's all about covers and 1st appearances.
Isnt JL 40 the first Grail?
Yes, but that was not the point he was making. When I tried to coax that 1st appearance out of him, hell fell flat on his face.
More likely he expected that you would do your own DD on these, or he didn't have the time or energy to fill in the blanks for you
Grail? Everyone knew about her a year ago. Almost a year to the day because of when the FCBD Divergence came out. She will be an appearance worth having some day. Could be next week could be in 5 years.
Did you even read his post???
Watch Saturday.
DC will announce formally that Rebirth spins out of Darkseid War, even though the info is out there informally.
Jusstice League #40-48 will go nuclear then.
Not today.
Saturday.
Can we expand on the sss's in Justice to hype it a bit more?
Jussssssssstice League 40-48!!!
