I made an account in order to share this information with you guys:
I was checking this video that shows of some of the technology of the game. One of the debug screens contains the information as shown in a link I can't share because my account is too new.
But you can see it in the below YouTube video.
The moment in the video starts around the 3:32 minute mark, here:
As far as I know the inclusion of Shiva was heavily expected and theorized but not really confirmed (correct me if I'm wrong). But we can clearly read that she's present on that screen.
More interestingly we can see that Noct has 7 Summons in his repertoire during that segment. This could mean two things:
- There are 7 Summons in total, of which Ramuh, Titan, Shiva and Leviathan are confirmed. That makes 4 3 out of 7. If you count Carbuncle and Leviathan as well, that makes 5 out of 7. That leaves 2 to 4 Summons to still be found.
- There are at least 7 Summons and during this demonstration Noct simply doesn't have all the spells, weapons, abilities, and Summons in his repertoire. There might be a few more Summons out there which are either not finished, or simply not included in that "7" that Noct has during this demo.
Either way, I'm already very pleased with knowing there's at least 7. That might not be as much as certain older FF's, but Tabata had already confirmed that there wouldn't be a lot. I was afraid that would mean about 4 or 5, so 7 is already a decent amount. Especially considering they're big deals to acquire and to Summon. They're not simply random spells and abilities you can use nilly willy.
