Fuji shows a mockup of a modular GFX system mirrorless camera

Fujirumors spotted this interesting new video from a Fuji event in Dubai. There is a lot of discussion about the sensor size and Fuji future products. And for the first time Fuji did show this modular GFX camera that they have developed. This is not ready to get into production yet but Fuji hopes that eventually it will:

On that core module you can attach different grips or different EVF’s. The sensor and back LCD screen are fixed. I hope Fuji will extend the modularity to the sensor too. Would be nice to be able to upgrade the sensor too!

Do you like Fuji’s idea?
