Wow, that's a lot of questions! While I can't offer timelines on any of these, I can tell you we do have plans to do the Septuagint, and we'll eventually do an NA Greek NT -- just not sure which version yet, a lot depends on licensing.
I don't know off hand which texts our Hebrew is based on -- I'd have to research that.
We will probably offer the Lutheran Confessions, and I'm not sure what BAG is.
Right now we're working on Zodhiates' Complete Word Study Old Testament and New Testament (if that's any help.)
