I don't see any posts on this but Volume 4 is in the last 2 weeks on Kickstarter and it's struggling to gain momentum. I have volumes 1-3 and they are outstanding! Yes, POTF and EU, and E1 figures aren't as nostalgic as the OG figs but I'd still love to see this book get made. Check it out and for those who missed previous volumes, there are options to buy them.
