According to latest rumors Sigma may announce new M4/3 camera with Foveon sensor, BTW we already have a large array of M4/3 lenses + cameras available, so if Sigma jumps on the M4/3 ship… it will bring a new profit opportunity for sigma and more choice for a M4/3 users.
Why I think this rumor isn’t true
Fact #1 Few years ago Sigma said “they had no plans to make MFT cameras”
Fact #2 The current APS-C Foveon sensor (SD1 Merrill DSLR) is almost outdated, the sensor show significant amount of noise starting from ISO 1600 and so on, Sigma cannot move to M4/3 format with existing Foveon technology.
