We can only release so many collections every month and every year. There is only so much money in the marketplace to allocate for such things.

So we make our publishing choices based on what we think is likely to do well at a certain point, and what has done well in the past.

Volumes of certain books may come about more quickly because those books have sold better, and the demand is clearly there. Other books may never receive a follow-up volume, if sales were poor. It varies completely from case to case and situation to situation.

Long story short, I have no idea when, or even if, we’ll be doing another Big Time Ultimate Collection.
