[quote name='DNukem170']Should have been clearer. Does the current DTB have separate cases in one box for the two formats, or are they packaged together in one giant bloated box?[/QUOTE]
It's usually split between two boxes, one for the blus and one for the DVDs, but sometimes it's also tricky because they will have one box for both disc 1 of the blu and DVD, and another box for the blu and DVD for disc 2. It's really strange how they package them, so it'll be just what you get from each one since each package comes differently like that.
But yeah, sorry I didn't get what you were saying before, but hopefully this is more relevant to your question.
*edit*
Also after re-reading I guess I still wasn't as clear as I wanted to be. There will not always be a case for blus only or DVD only, but there will be two separate cases unless it's an OVA which generally just comes in one single case with both DVD and blu inside.
Each series will be different in packaging the two separate cases, whether it will be the ones with DVD and blu separately, or the ones that has a box for the disc 1s and disc 2s of the DVDs and blus.
It will be dependent on the series how your cases will be split up if they are split up..
Hope this is more clear, lol.
