If Eidolons are in this game - which ones would you like to see?

[Formalhaut]

For me the trusty Shiva. Perhaps even a surprise appearance of some Espers such as Zodiark.

I doubt it, the espers are sort of specific to FFXII and are tied to that world. In other words, their all original, new, one-time espers.

Bahamut would be the obvious choice, what else? I love Alexander, easily my favourite summon.
