Meh, I like the new holos, but I miss the cool quotes and the cool insert pictures just after the cover. They were like an inside look as to what to expect of the book. Also I hope that they move on to full body holos, that'd be even cooler.
I think the watermarks would be good to use to help identify at quick glance who's narrating the book. Though as long as they design the future watermarks on the animal in the holo, they should do well in not repeating marks.
