I’m praying for no prequel references. That’s all. I honestly don’t care about anything else.
Johnson is a noted prequel devil’s advocate. There’s little chance he’ll litter the film with references, but if the Jedi is to be a large part of it (and at this point that’s probably a safe assumption), then one can expect a passing reference or two to the old Jedi order. And if that’s the case, there’s no way it won’t align with what’s in the prequels.
So yeah, don’t expect the film to be devoid of PT references, though I doubt there’ll be too many more than in TFA.
