Sigma Poland has published a new website called Sigma Foto Revolution (rewolucja.sigma-foto.pl) that has a running countdown and a slogan that translates to "Destroy the system with Sigma, release is coming" or something like "Overthrow the system with Sigma, there is liberation". The use of the word "system" is very interesting. On several occasions in the past, Sigma has officially said that they will not pursue a mirrorless interchangeable lens camera (see this and this posts).
