Its a feature not a fault. The camera was extensively tested on Mt Fuji in winter where the original alpha testers fingers were getting too cold. Rather than provide the testers with gloves or heat packs Fujifilm decided to install a little fire imp inside the camera body in order to provide the warmth required for extensive shooting in low temperatures. Admittedly there is downside to this in that in warmer climes or during summer the camera body can become slightly toasty.... not a problem,. This June Fujifilm will release the Gunmetal version of the X-Pro2 which has an ice imp installed instead. In fact that version has a little side hatch where, if you speak very nicely to the imp, it will dispense freshly made ice creams and slurpies. I hear tell that Fuji have decided to expand this idea for next Christmas by firmware update to allow the original black X-Pro2's fire imps to supply roasted chestnuts.
