So Greg  confirmed the current 8 will return. Lagoon Boy, Blue Beetle and Wonder Girl(where did they find these guys ) seemingly join the team. Beast Boy who is still 8 looks and he joins the team. I'm just gonna say  he'll take on the name  Vox. Vox is mentioned by Dick  and he knows about  zeta tubes so he must be on the team. That leaves the mysterious gold blue girl,  Bumble Bee and Bat Girl. If no one on the team dies     and the last 3 mentioned  join up. the team will be a total of 16 members   1. Robin, 2. Aqualad, 3. Kid Flash, 4. Superboy, 5. Miss Martian, 6. Artemis, 7. Zatanna, 8. Rocket, 9. Blue Beetle, 10. Lagoon Boy, 11. Wonder Girl, 12. Beast Boy, 13. Vox, 14. Bumble Bee, 15. Batgirl 16. Gold Blue Girl. That is how many members of league there were through episode 1 - 24
