Well Diabolos be a summon/primal?

But these Egis will not appear until there's either a level cap raise or more abilities are added to every class because the number of abilities for each class/job is staying consistent...no special treatment.

From knowledge, not "or". "And". Level Cap raise AND new skills for all classes is what I believe they said. Would need a level cap raise to have it make sense in terms of progression, and all Jobs would need the same amount of new skills.

New EGI, though believed to be set in stone, don't really have any clearly defined "Yes"s from the developers. I do want Leviathan EGI though.
