I don't wanna knock it. But the Ent-D has had a LOT of coverage over the decades. From the Tech Manual to the CD-ROM of the Interactive Tech Manual (which also had a virtual tour of the ship), to various books and blueprints and deckplans, posters, illustrations, not to mention tons of outstanding fan work on the internet. A LOT of material.
Haven't we already seen all kinds of schematics, cutaways, and so on? What more can the Okudas bring to the table that we haven't already seen?
Like I said, I'm not knocking their efforts. I'd love to see more new original Ent-D stuff. I'll be first in line to buy it.
But I don't know if I need to see more plan/elevation views and cutaways that I've seen dozens of times in other materials.
