I'm happy to do some translating of Vol. 2 as well. There are a few things of particular interest to me right off the bat: any new LTD quotes (of course), new details on Ultimecia and/or the Succession of Witches, anything new on Ozma or Necron.
I'm also curious to see if there's any new concept art for FFVIII.
I wasn't particularly interested in the other two books for a few reasons:
-None of the other games really have any story details I feel a powerful desire to see elaborated upon further
-I find Amano's art hideous (so this rules out any remaining need for the first book)
-I don't really give a shit about FFXI, and absolutely no fucks given about XIV (so, two of the five games detailed in the third book are irrelevant)
-While FFX is one of my absolutely favorites in the series, if there's any plot details, character history or artwork I don't already have between the FFX Scenario, Battle and Omega Ultimanias -- or in one of the three FFX-2 Ultimanias I own -- then I don't really need it at this point
-I kind of feel like hito has already shared plenty of relevant stuff from XIII's Ultimania with us -- and given the way each sequel to the game is determined to drive the plot further into nonsense, it probably doesn't much matter at this point anyway what Ultimanias have to say about the game's story beyond what we've already picked up on; XIII-2 felt so far removed from the original, I hardly cared, and Lightning Returns looks to be going even further down that road
-The first one covers six games and is only 336 pages, so that's about 56 pages per game; the third one covers five games and is also only 336 pages -- about 67 pages per game; Vol. 2 is 320 pages, and should be able to offer 100 or more pages for each of the three games it covers
