If you ever plan on uploading prototype pics onto the internet or sending Kotaku secret factory photos, there's one thing you must remember: modern day electronics have reflective surfaces.
Codenamed "Pepper", the Xperia MT27i's newly leaked specs aren't nearly as impressive as the rumored specs for the Xperia LT28at, Sony's upcoming "super phone": 3.7-inch display and 5-megapixel camera as opposed to the LT28at's rumored 4.55-inch display and 13-megapixel camera.
Japanese web forum 2ch was quick to point out that the individual who leaked the photos on a Chinese forum appears in said leaked photos. His reflection is visible in the reflection.
2ch commenters assumed that the individual snapped photos in a Chinese Sony factory, but with CES around the corner, these could have been taken anywhere. (2ch also largely derided this Xperia as "not cool".)
Previously, a worker at one of Sony's Chinese factories apparently leaked the first PS3 Slim photos back in May 2009. The PS3 Slim, however, didn't have a shiny surface, sparing that mole internet infamy.
