Well, its interesting though about the ten wizard saints Cali now that you mentioned it.
You have the Four Heavenly Gods of Ishval who so far only one was shown, Cken. Then you have Jura and Makarov. Jose and Jellal were removed. That leaves 2 normal ones and 3 heavenly gods of ishval to be shown. Its indeed possible that they will have a bigger role now that the whole council is in shambles and that it appears nothing will work if someone doesn't take charge.
We can't also forget, the other guild masters, from the guilds associated with FT and even those who we saw in the magic games. Its possible that to fight Tartaros, we'll see a return of those in some sort of alliance.
