The FF250003 just showed up on Weibo, and the FF250001 was found a few months ago here. The Fujifilm GFX100RF ended up being the FF250004, so the FF250003 and FF250001 are currently unaccounted for, but we know one of them will be the Fujifilm X-E5, probably the FF250001 since it has a multiband wireless system compared to the FF250003 which has single band wireless, which is typically found in lower end cameras.
If you think the Fujifilm X-Half Frame is the other unannounced camera, it is not because we know for sure that the Fujifilm X-Half Frame is going to be the FF240003 based on numerous big leaks.
