Wow, am I ever glad I got out of the house this afternoon! š
A double dip with new extras timed to the next film in 2017 seems likely. Has JJ done many commentary tracks? (I only have Trek '09 besides TFA.) I would be more interested in a cast commentary at this point though.
Into Darknessā track was a digital exclusive, so is 10 Cloverfield Lane (which he only produced), but Super 8 has one on disc. It may be just a timing thing.
