I agree with Paul, it is a wish they (Sigma) have and are working towards, but nobody knows the time table. Why you ask? Sigma recently changed their process in creating a sensor about 2 years ago after they purchased Foveon which should shorten their plan to product transition phase is shorten, but it is still too early to tell by how much and start to make predictions on how long it will take.

It would be surprising to see anything before 2015.

I think it is overall hard to tell, since SD1 seems to be the only sensor Sigma has made with the new process and we don't know exactly when they started and also what all they will need to account for in developing a full frame. You may very well be right, I have no basis to make an estimate.

I personally hope that their full frame sensor (if that is their next sensor and not another crop like a 1.3) is not 2.25x the resolution of their current sensor. I think the pixel density is too high for me, most of my EX (Pro Glass, like L series) lenses wouldn't be great for such a high resolution sensor.

But the sensor should be better than your best lens. Then you know that you are getting all the detail the lenses can give.

If like the SD1/SD1M in being that much better, the lens will actual blur details if it is not up to it. I would like the sensor to outperform the lenses, but hopefully not at the amount that I feel I need to replace my collection of good full frame EX glass lenses.

I rather a little sacrifice of pixels for a more usable sensor overall that would allow a little better ISO sensitivity with higher quality (each ISO step will have better image quality) and faster operation (more photos fit in the buffer). 25mp to 28mp full frame would be awesome, I would jump at the camera very quickly

Certainly the Foveon sensors need less noise (= higher ISO).

Exactly, I want a combinition of higher ISO capability, but I really also want to see much better performance at each ISO level (i.e. 100, 200, 400, 800...etc). It doesn't need to compete with Bayer, but if you could get a decent image at ISO 6400 and be able to fully use ISO 9600 or ISO 12800 for black and white, that would be awesome.
