Looking on the S-E website I've seen the listing for an upcoming Final Fantasy VII Ultimania Guide:
Manga & Books | SQUARE ENIX
Square Enix, renowned for FINAL FANTASY and NieR game series, offers lots of manga with anime adaptations like Soul Eater and game tie-in books in English.
squareenixmangaandbooks.square-enix-games.com
Packed with art and visual reference materials used during development of the game, this deluxe, hardcover volume is a must-have for fans of hit video game Final Fantasy VII Remake.
Final Fantasy VII Remake: Material Ultimania presents a comprehensive collection of production and CG art assets, including character models and illustrations, locations and backgrounds, accessories, weapons, enemies, and more, all accompanied by staff commentary. This volume also includes detailed costume references, cutscene storyboards, song liner notes from the sound staff, and Q & A interviews with the Japanese voice actors.
At over 300 pages, this full-color, jacketed, hardcover book is a visual tribute to the stunning new rendition of one of the most beloved RPGs of all time.
Considering this is advertised on the UK/EU & USA Website I think it is safe to consider this is translated? Another listing seems to confirm this!:

How exciting! I hope this is a new standard as I have always wanted to gather these - if Studio Bentstuff or Dark Horse want to translate previous releases still I would be all for it! Still, this is a great step forward to getting these wonderful FF Encylopedias!
