First, I hope so. Second, why not? Third, I think it's going to happen because I don't see how else you can read these quotes from Newsarama:
"Giffen: No, no. It's Beetle and Booster. This is them. Basically, a cryogenic chamber is found on Takron-Galtos while they're excavating, and inside are Beetle and Booster. It's Ted and Michael. It's really, really them. It's not clones. It's not the parasite thing.
It's not a trick. It's not an imaginary story.
Nrama: But… those characters are from before the New 52 reboot.
Giffen: That's right. So what does that have to say about what universe Justice League 3000 is taking place on? Maybe a universe where, if you went back and looked at Superman in the 21st Century, he might be wearing his underpants on the outside.
But before you get too excited, remember that in this universe, Beetle didn't get shot in the head.
Nrama: OK, so what I'm hearing is, Justice League 3000 doesn't take place in the future of the New 52 universe. It takes place in the future of a universe that's like the pre-New 52 universe — where Blue Beetle is Ted Kord, and he has the familiar history with Booster Gold. And this is really those two characters.
Giffen: Yes. It's actually Blue Beetle and Booster Gold."
