There is far more to image quality than the pixel density and Mp rating of a given camera. If this rumor is true regarding a FF 14 Mp FF chip, all things being equal it should have the low light capability to rival the D3s and 1DMk4. There is the issue of optimizing the in camera processing of images as you allude to. If Sony can utilize the processing of the A550 in a 14 Mp full frame camera, they may finally have a low light camera to brag about.
Combine this chip with a new, better AF system in an A900 size body and Sony could make a product to rival the D700 and 5DMkII.
However, I doubt this rumor is true. Time will tell.

I'm missing something. The A700 has 12.2 Mp in an APS-C format. If the 750 has FF 14.6 MP it is the FF equivalent of a 6.5MP APS-C camera. I remember when the KM 7D came out there was all this wailing and nashing of teeth because it was only a 6Mp camera when the equivalent Canon was 8Mp.
What is the advantage of going FF with only 14MP? Yes, you gain the full use of wide angle lenses. That was a valid need when the smallest FL lens readily available was 20mm. But today there are many newer lenses with very small FL.
Noise should be lower because of the larger pixel size, but it typically comes down to the algorithms and choices used in the cameras. Considering that the 500/550 are supposed to have better noise considerations than the 700 with at least the 700's pixel density, I don't see why they would want to decrease pixel density of a FF camera to about to 1/2 of the 500/550 series
If this were to come out, the Canon folks would have a field day talking about Sony taking 2 steps back ('Sure they can make cheap cameras, but they used to be about quality')
