It's been noted in the DC Message Boards that the "Super-Sons" lived on Earth-154, and the Debra Winger/Cathy Lee Crosby Wonder-World was Earth-462. Alex Luthor combined these two Earths, and came up with Azteca-themed Super/Bat/Wonder families engaged in a clan war. He promptly discarded it.
The reason for this failure? Perhaps because Earth-154 + Earth-462 = Earth-616, the homeworld of the Marvel Universe whose heroes are now immersed in a "Civil War"?
That's one obscure piece of numerology right there. Seriously, how do people CATCH things like that? It's like I've always wondered who it was that first discovered that 'Dark Side of the Moon" can be synched to THE WIZARD OF OZ.
I think what Geoff Johns meant to show there was that Earth-154 was the Super-Sons Earth. The reason is that in Alan Moore's proposal for TWILIGHT OF THE SUPER-HEROES, and even in the concept art, there is no mention anywhere of Batman having a "son." In fact, Batman had no House the way Captain Marvel and Superman did; he was a mysterious faction working with the old 1930s pulp guys like the Shadow and Tarzan. Nonetheless, that was still cool to see.
And I'm tickled pink that Geoff Johns remembered Stanley and his Monster. Funny how in the wake of all the explosions and space battles, it was a little thing like that, that made my day. The suggestion that magic is weird now in the wake of the Spectre is an excellent build-up to the use of the Michael Moorcock "Magic Bible." Anyone who knows me knows I love Moorcock. The idea of him writing a magic bible for how magic works in the DCU is a very pleasant surprise.
I absolutely loved this issue because of the almost palpable friendship that the characters share. Batman and Green Arrow's exchange, "Just to see if you'll show." Wow. And Black Lightning and Mr. Terrific bonding as they ran into the interior of the ship. The idea presented here is an interesting characterization: Black Lightning was one of the few black superheroes and was proud of his race, and so as a result of this, he gave himself the name "Black" Lightning.
Though this Mets fan was slightly disappointed to learn that Hal Jordan and Ollie Queen were Yankees fans. Boo!
