Extending that question, it would also be interesting to know how creative control is split between Bioware and Lucasfilm, and if (or how) that is expected to change; but it's probably way too early to ask that.
He actually went into that a bit on the podcast (TORWars?) that interviewed him. Basically BioWare has a lot of creative control because they kind of carved out the era for themselves early on, but LucasArts still reads and vets everything to make sure nothing contradicts the greater lore. Who knows if that would ever change.
