I haven't read through the whole of this thread, but someone suggested I should voice my opinion, so here I am.
I actually wanted the five separate volumes. I might not actually go for the printed run, now. I don't know about anyone else, but it's pretty unwieldy for me to handle that much book at one time when actually trying to READ it. I have a volume that has three books in it, and it's smaller by word count than the proposed two Fo:E volumes would be. I rarely read it because it barely fits in my hands, it's extremely difficult to turn single pages at a time, and it causes a great deal of wear on the spine and binding every time I sit down with it. I'd rather pay more for five volumes than compress it down to two just to save a bit of money on printing and shipping.
Maybe I'm alone in that opinion (again, I haven't really read the whole thread, just the original post), but there it is. If the new round of printing goes with the two volumes, alright. But I'm going to have to pass, unfortunately. A shame, really. I missed the first run, and I really wanted a hard copy of Fallout: Equestria, but I'm not going to pay for a hard copy I literally can't use.
