Eldor still has a big chance to be made i think. He, Darius and Maras prototype status makes them very likely to be included in the new roadmap.
Queen Veena on the other hand? I´m not sure about that. As much as i want her plus her mini comic appearance with clear MOTUC references made her arrival more possible but in the end we simply have to wait and see.
But i´m not giving up hope
