Bismarck and Lakshmi are summons from FFVI.

So, we might expect one completely new Primal and one existing one. We know we'll have the Nu Mou beast tribe and they also mentionned Dwarves, but I'm not sure what existing Summon you could really tie to them, especially since Ultima (The Nu Mou Totema) is not available anymore.
