I thought they had several books done, back when they were still looking to do the Giant Size Line of free comic books.
I also think they should go for shorter story arcs, less expensive trade paperbacks.
If REDG doesn't have enough books to complete trade paperbacks now, they should cut the production line and support the most likely to succeed books, on a monthly schedule.
Mixing monthly, bi-monthly and quarterly books in the production is a recipe for failure.
But, I'm sure that there new board member probably approves of the current plan.
