Fujifilm has patented the following lenses for full frame mirrorless cameras.
My guess: probably some cine-lenses for other mounts.
UPDATE: FR-reader Mistral75 says:
This patent is related to the Fujinon Premista 28-100mm T/2,9.
Look at the image circle diameter of the examples in the patent: 46.3mm. A bit more than the diagonal of a regular 24×36 sensor (43.3mm), 46.3mm is the diagonal of the 40.96mm x 21.60mm 8K RED Monstro VistaVision sensor used by the RED Weapon Monstro and Panavision Millenium DXL cinema cameras.
