Mirrorless rumors from others: NEX roadmap and NX lens release (+ Sigma surprise?)

I once heard from a trusted source that Olympus also tested Sigmas Foveon sensor on one of their Micro Four Thirds prototypes. I haven’t heard anything since then. But I remind you that Sigma is member of the Four Thirds coalition. So let’s be careful about the following Sigma rumors although I don’t believe they will make a Micro Four Thirds camera ;)
Mr. Rytterfalk writes: “in a few month we will (I still hope for Feb) see the new Sigma SD1 which is really the result of years and years of dedicated hard work – The new generation of sensors that will come out from the Foveon labs and starting with the SD1, are for sure the most interesting things sensors since the original SD9 and for the first time I really feel that this will change how people look at Sigma and three layered photography in general.
I would love if Sigma would join the Micro Four Thirds system with an interchangeable SD camera. But that is probably a dream only. Anyway, if Olympus really tested foveon sensor why not let us hope that Sigma will do sensors for a future MFT camera?

And Let’s take a quick look into the mirrorless competition. Andrea from SonyAlphaRumors posted the possible Sony NEX roadmap. With the announcement of the new NX lenses Samsung created high expectations. But according to latest info posted on X-rumors those lenses will be available much later than expected.
