Bayer sensor and MX

The way the Bayer sensor works, it "makes up" color information depending on
the surrounding pixels. But if you do multiple exposures with exactly the
same scene, the picture gets more sharp according to the amount of
exposures.
Much is due to the fact that noise is distributed randomly and hence, the
same place where a "piece" of noise was before, it's over written with data
the next exposure.
What I was wondering: do the pixel interpolation always work the same way?
Or is this also slightly random (shifting)? So do you, in fact, get more
information or only less noise? It just seems hard to believe, that every
take of a picture would give exactly (I mean pixel deep peeping) the same
result.
And also: do all Bayer sensor work exactly the same, or is there a
difference in Nikon, Canon, older, newer models?
