As the post says I wish pre-pubs "in production" could be made available as ebooks. As an example I ordered a John Lennox book nearly 2 1/2 years ago when the book was published. It's been out so long now that I was able to buy today as a Kindle ebook for £0.99. I've have therefore canceled my pre-pub order and will only now buy the Logos edition if it goes on sale in the future. I'm sure there must be a way for Logos to release books in ebook format while they're developing the fully functional research editions. This way Logos would also get money upfront to fund the development.
