Book: 512255 Pokémon: Das große Lexikon (Source: Brickmerge)

So, at first it seemed strange it didnt look like lego, the cover didnt have anything lego but looking into it the cover mentions it being preliminary, another website that had this ltoys had other pokemon books but they were all pokemon branded this (ean 9783845122557) was listed as being lego brand, looking up the ean number led into a ebay page which did not mention anything lego same preliminary cover, it costed 18 euro on both sites, brickmerge said the release was 2025, however if it was i would think its late 2025 to maybe build up some hype,
